Factory Direct Sale Customized Metric Full Thread M6 M8 M10 Stainless Steel Hex Head Bolt
Procurement teams, mechanical engineers, and hardware distributors who begin a search with the phrase factory direct sale customized metric full thread M6 M8 M10 stainless steel hex head bolt are usually chasing one goal above everything else: a dependable, repeatable supply of standard fasteners at a manufacturer's price. That long query actually describes a tightly defined product, a metric thread, a fully threaded shank, a hexagonal head, and a stainless steel body that resists rust in demanding environments. Hex head bolts have remained at the centre of industrial assembly for more than a century because they are simple to drive, easy to torque to specification, and straightforward to inspect with a visual check. Diameters M6, M8 and M10 are the three most frequently ordered sizes in light and medium engineering, covering everything from control cabinets and furniture frames to solar mounting rails and pump housings. Buying directly from a factory removes the trading layers that inflate prices and slow down communication, so the buyer speaks with the people who actually run the machines. Qiǎnsheng Metal Products Co., Ltd., located in Yongnian District, Handan City, manufactures and exports precisely this category of fastener. The sections that follow explain the product, the materials, the tolerances, the customization options, and the commercial terms you should expect when you place an order.
Why Choose Qiǎnsheng Metal Products Co., Ltd. in Yongnian District, Handan City
Yongnian District in Handan City is one of the densest fastener manufacturing clusters in the world, with thousands of workshops, cold heading machines and plating lines operating within a few square kilometres, which means raw material, tooling and skilled labour are all available locally. Qiǎnsheng Metal Products Co., Ltd. grew up inside that ecosystem, and the location gives the company clear advantages in cost, speed and technical know-how. The business has accumulated roughly twenty years of experience producing bolts, screws, nuts and construction accessories, and it now serves customers across Southeast Asia, the Middle East and other export markets. Its product range is deliberately broad, spanning standard fasteners, aluminium formwork accessories and general building materials, so a single supplier can cover several purchasing categories at once. You can review the complete catalogue on theProducts page or follow company developments on the News page. Because the factory controls heading, threading, heat treatment where required and surface finishing in-house, quality problems are identified and corrected quickly instead of being passed between subcontractors. That vertical control is the real foundation of the company's reputation with repeat industrial buyers.
Working with an established manufacturer also removes the risk that comes with anonymous trading accounts. Many overseas buyers have learned the hard way that a very low quotation from an unknown middleman often hides a thinner material grade, a shorter thread length or a delayed shipment. Qiansheng answers those concerns with documented material certificates, measurable inspection records and a named contact who owns the order from first inquiry to final delivery. The engineering team can review your drawing, suggest a more economical standard equivalent, and confirm whether a non-standard length or head marking is feasible long before you commit any money. For buyers who need a long-term partner rather than a one-off shipment, that technical dialogue is usually worth far more than a few dollars saved on a single container.
Product Overview: Metric Full Thread Hex Head Bolts in M6, M8, M10
A metric full thread hex head bolt is a threaded fastener with a six-sided head and a shank that is threaded from tip to head, leaving no plain section under the washer face. In the common coarse series, M6 uses a 1.0 mm pitch, M8 uses a 1.25 mm pitch and M10 uses a 1.5 mm pitch, all of which conform to ISO 261 and are interchangeable with most international hardware. Head dimensions follow familiar standards as well: M6 typically measures 10 mm across the flats with a 4 mm head height, M8 measures 13 mm across the flats with a 5.3 mm head height, and M10 measures 17 mm across the flats with a 6.4 mm head height. These sizes match standard socket and spanner sets worldwide, which keeps installation fast and tooling costs predictable on any production line. Full threading is a genuine functional benefit rather than a cosmetic detail, because it lets the bolt clamp at any point along the shank and suits joints where plate thickness varies from unit to unit. Lengths are normally stocked from 10 mm to 100 mm, and any intermediate length can be produced on request. Every batch is gauged for thread fit, straightness and head concentricity before it leaves the factory floor.
Choosing between full thread and partially threaded bolts is an engineering decision, not a price decision. Partial thread bolts are stronger in shear and are often specified for structural steel connections, while full thread bolts shine wherever adjustability and a short grip length matter. A full thread design also eliminates the risk of running out of thread when two or more components are clamped together, a problem that frequently appears in retrofit and repair work. For electrical enclosures, instrument panels, adjustable brackets and modular racking, the full thread metric hex head bolt is usually the simplest correct answer. Qiǎnsheng produces both configurations, and the sales team will tell you honestly which one suits your joint rather than simply quoting whatever is already on the shelf. That kind of advice saves customers time, material and rework costs.
Material & Finish: Stainless Steel Grades 304, 316, 201 and Corrosion Resistance
Stainless steel is the reason these bolts survive outdoors, in wash-down areas and in coastal installations where carbon steel would rust within weeks. Grade 201 is an economical austenitic stainless steel with manganese replacing part of the nickel, and it offers good mechanical strength with moderate corrosion resistance for indoor and dry-service applications. Grade 304, also called A2, is the workhorse of the family, delivering excellent resistance to atmospheric corrosion, fresh water and most organic chemicals. Grade 316, known as A4, adds molybdenum, which dramatically improves resistance to chlorides, salt spray and marine atmospheres. All three grades are non-magnetic in the annealed condition, although cold working during heading and threading can introduce slight magnetism, which is normal and does not affect performance. Qiǎnsheng stocks all three and will recommend the grade that matches your environment instead of upselling you to 316 for a dry indoor assembly.
Surface finish matters just as much as the alloy, because a damaged or contaminated surface is where corrosion always begins. Standard supply is a clean, passivated, natural finish that removes free iron from the surface and restores the protective oxide layer. Polished, brushed and electrolytic bright finishes are available when appearance is part of the specification, for example on visible furniture hardware. Salt spray testing is used to verify performance, with 304 typically passing 48 to 240 hours and 316 reaching 480 hours or more depending on surface condition and test concentration. Bolt markings are stamped or forged on the head so that grade and manufacturer can be traced during inspection. This traceability is important for projects that require documented material conformity.
Customization Options: Size, Thread Pitch, Length, Head Marking, Packaging
True customization goes well beyond choosing a size from a catalogue, and Qiǎnsheng treats it as a core service rather than an inconvenience. Diameter can be produced from M3 upward, so buyers who need M6, M8 and M10 in the same shipment can consolidate everything into one order. Thread pitch can be coarse or fine, and non-standard pitches are possible with dedicated tooling. Length is cut to the millimetre, which removes the waste that comes from buying the next size up and trimming it on site. Head markings can carry your own logo, grade code or part number, an option that is popular with distributors and OEM assemblers who want their brand visible on every component. Packaging is fully configurable as well, from plain bulk cartons to labelled polybags, blister packs, and printed boxes with barcodes. You can explore the full scope of these options on theCustomized Service page.
Customization is most valuable when it solves a real production problem rather than adding decoration. A customer assembling solar mounting rails, for example, may need a specific length that avoids contact with the panel frame while still accepting a nylon locking nut. Another may need a slightly reduced head height to clear a rotating component inside a gearbox. Qiǎnsheng's engineering team reviews these requests against tooling availability and cycle time, then confirms what is genuinely achievable and what would be disproportionately expensive. Because the factory machines its own tooling, small-batch customization stays affordable and does not require a container-sized commitment to begin. Buyers regularly start with a trial quantity, validate the part in the field, and scale up once the design is locked.
Quality Control & Standards: ISO, DIN, ANSI, GB, Tensile Testing, Salt Spray
Fasteners are safety-relevant components, so a documented quality system is not optional for serious buyers. Qiansheng operates under ISO 9001 principles and manufactures to internationally recognised dimensional standards including DIN 933 and ISO 4017 for full thread hex bolts, ANSI B18.2.1 for inch-series equivalents, and GB/T 5783 for the domestic Chinese market. Raw material arrives with mill certificates and is verified against the declared grade before heading begins. In-process inspection covers head formation, shank straightness, thread rolling and length, with go and no-go thread gauges used at defined intervals throughout the shift. Mechanical testing includes tensile strength, proof load and hardness checks, which confirm that the bolt will carry its rated load without permanent deformation. Corrosion performance is validated through salt spray testing, and full inspection reports are retained against each batch number.
The details of a quality system are what separate a genuine manufacturer from a reseller who never sees the product. Dimensional checks are recorded with actual measured values rather than a simple pass or fail tick, so a customer can see how close the production run sits to the tolerance limits. Where a project requires third-party inspection, the factory cooperates with nominated agencies and prepares the samples, paperwork and access they need. Any non-conforming batch is quarantined and traced back to the specific machine and material heat number, which allows root-cause correction instead of guesswork. Retained samples from each order give both parties a physical reference if a dispute ever arises about dimensions or finish. This level of discipline is what allows Qiansheng to keep supplying the same customers year after year.
Competitive Advantages: Factory Direct Pricing, Fast Delivery, OEM/ODM, Bulk Supply
Factory direct sale pricing is the most obvious advantage, because every intermediary removed from the chain is a margin that stays in the buyer's pocket. There is no trading company markup, no double handling and no re-labelling cost, and quotations reflect the real cost of steel, energy and labour at the source. Fast delivery follows naturally from that structure, since production scheduling does not depend on a third party's order book. Repeat sizes such as M6, M8 and M10 are commonly held in stock for immediate despatch, while custom runs are scheduled within a clearly communicated lead time. OEM and ODM support means a buyer can arrive with a sample, a drawing or even just a functional requirement and leave with a manufacturable specification. Bulk supply is handled as a core competency rather than an exception, with capacity reserved for customers who order consistently.
Cost leadership alone is not enough in a market as competitive as fasteners, so the company pairs price with responsiveness. Questions raised during quotation are answered by someone who can walk onto the production floor and check the answer rather than guessing. When a customer's design changes late in the project, the factory can usually adjust tooling and continue without restarting the entire approval process. Distributors benefit from consistent packaging and part numbering that make their own warehouse operations simpler. Project buyers benefit from consolidated shipments that combine bolts, nuts, washers and formwork accessories in a single container, reducing freight and customs overhead. All of these small operational advantages compound into a lower total cost of ownership rather than merely a lower unit price.
Applications: Construction, Machinery, Automotive, Marine, Furniture, Solar Mounting
Metric stainless steel hex head bolts appear in more industries than most buyers initially expect. In construction, they secure formwork panels, scaffolding clamps, handrails and façade brackets where weather exposure makes stainless steel the sensible choice. In general machinery, M6 to M10 bolts hold guards, covers, brackets and control panels in place, often where vibration resistance and easy service access both matter. Automotive and transport applications use them for interior fittings, battery enclosures and aftermarket accessories where corrosion from road salt is a constant threat. Marine environments place the heaviest demands on the material, and grade 316 bolts are routinely specified for deck fittings, railings and dock hardware. In furniture and shopfitting, stainless hex bolts provide a visible, industrial aesthetic as well as structural strength. Solar mounting systems rely on them for rail clamps and panel frames that must survive twenty-five years of sun, rain and thermal cycling.
Each of these environments imposes its own combination of load, vibration, temperature and chemical exposure, and the correct specification differs accordingly. A furniture application may be perfectly served by grade 201, while a coastal solar farm will quickly destroy anything less than 316. Machinery that vibrates continuously usually benefits from a locking element such as a nylon insert nut or a thread-locking compound, and the bolt length must be chosen to allow for that. Where dissimilar metals are joined, isolation washers can prevent galvanic corrosion and extend the assembly's service life. Qiǎnsheng's team routinely discusses these variables with customers before finalising a specification, because a two-minute conversation at quotation stage frequently prevents a costly failure in the field. That practical application knowledge is one of the quieter strengths of an experienced factory.
Ordering & Shipping: MOQ, Samples, Lead Time, Export Packaging
Ordering from the factory is deliberately straightforward, but a few commercial details are worth understanding before you send an inquiry. Minimum order quantities are flexible and depend on whether the item is a stock size or a custom run, with stock sizes available in smaller trial quantities. Samples are normally provided so that buyers can verify dimensions, finish and thread fit before committing to volume production. Lead times for standard sizes are typically short, while customized bolts require tooling and inspection time that is confirmed in writing at the quotation stage. Export packaging is designed for long sea voyages and includes moisture barriers, strapping and palletisation suited to container loading. Shipments move through major Chinese ports with documentation prepared for the destination country's customs requirements. Inco terms, labelling and pallet specifications can all be adjusted to match your receiving process.
Clear communication during the ordering stage prevents almost every problem that can occur later. Buyers are encouraged to send a drawing or a physical sample, and the factory will confirm back the exact specification, tolerance and finish it intends to produce. A pre-shipment inspection report with photographs is issued before the container is sealed, so there are no surprises when the goods arrive. Where a customer has an existing supplier format for packing lists and invoices, Qiǎnsheng can generally follow it. For first-time importers, the export team is happy to explain documentation, customs codes and typical transit times. Support channels are listed on theSupport page for anyone who prefers to talk through the details before ordering.

Frequently Asked Questions (FAQ)
What exactly is a factory direct sale customized metric full thread M6 M8 M10 stainless steel hex head bolt?
It is a stainless steel bolt with a metric thread, a hexagonal head and a shank threaded along its entire length, produced at diameters M6, M8 and M10 and sold straight from the manufacturer. "Customized" means the size, pitch, length, head marking, finish and packaging can be adjusted to your drawing. "Factory direct" means there is no trading company between you and the production line, so pricing and lead times reflect real manufacturing costs.
Can you produce customized metric full thread hex head bolts in M6, M8 and M10 with my own head marking?
Yes. Head markings can carry your brand name, logo, grade code, part number or a customer-specified symbol, applied during the heading process so the mark is permanent and legible. Tooling for a custom mark is a one-time investment, after which every batch carries the same stamp. This is particularly useful for distributors and OEM assemblers who want their identity visible on the finished assembly.
Which stainless steel grade should I choose, 201, 304 or 316, for a stainless steel hex head bolt used outdoors?
For dry, sheltered outdoor use, grade 201 is usually adequate and offers the lowest cost. For general outdoor exposure, rain and fresh water, grade 304 (A2) is the standard choice and performs very well. For coastal, marine or chloride-rich environments, grade 316 (A4) with molybdenum is strongly recommended because it resists pitting and crevice corrosion far better.
What is the minimum order quantity for factory direct sale metric full thread hex head bolts?
Minimum order quantities depend on whether you are ordering a stock size or a fully customized item. Stock M6, M8 and M10 bolts can be supplied in relatively small trial quantities, while custom lengths, pitches and head markings require a larger minimum to cover tooling and setup. Send your target quantity and the factory will confirm the most economical batch size.
How do I get a price for customized M6 M8 M10 stainless steel hex head bolts?
Simply send a drawing, a sample photograph or a written description that includes diameter, pitch, length, material grade, finish, head marking and expected quantity. The more complete the information, the faster and more accurate the quotation will be. Price is normally quoted per piece or per thousand pieces, together with packaging details and the applicable lead time.
Can I get samples before placing a bulk order?
Yes. Samples of standard sizes are normally provided so you can verify dimensions, thread fit, finish and head marking before committing to volume. For fully customized bolts, sample production follows tooling confirmation and may involve a modest setup charge. Once the sample is approved, that approval becomes the reference standard for the production run.
What is the typical lead time for a container of stainless steel hex head bolts?
Common stock sizes can often be prepared for shipment within a short window, while customized bolts require additional time for tooling, production and inspection. Lead time is always confirmed in writing at the quotation stage and depends on the total quantity, mix of sizes and finishing requirements. For urgent projects, the sales team will advise whether partial shipments can accelerate your schedule.
Do you provide quality certificates and test reports for your hex head bolts?
Yes. Material mill certificates, dimensional inspection records and mechanical test results such as tensile strength and hardness are available for each batch. Salt spray reports can be provided for corrosion verification, particularly for 304 and 316 grades. Batch numbers on the packaging allow the finished product to be traced back to the raw material heat number.
What is the difference between full thread and partial thread metric hex head bolts?
A full thread bolt is threaded from the tip all the way to the head, while a partial thread bolt has a smooth shank section between the head and the threaded portion. Full thread bolts offer greater adjustability and suit thinner or variable joints, while partial thread bolts are generally stronger in shear. Both types are available to order in M6, M8 and M10.
Do you offer OEM and ODM services for customized hex head bolt industry buyers?
Yes. OEM production builds to your existing specification, drawing or sample, while ODM support allows the factory's engineering team to help develop a specification from a functional requirement. Both routes include help with material selection, length optimisation and packaging design. This is especially valuable for importers building a private-label fastener range.
