The high-strength 100kN Q235 steel screw rod and disc nut assembly is manufactured to precise dimensional tolerances that ensure compatibility with standard mounting holes and structural framing systems used across the construction industry. Each screw rod is produced with a diameter range that accommodates the required load-bearing capacity while maintaining thread consistency throughout its length, allowing for smooth nut engagement and reliable torque application during installation. The Q235 steel material undergoes strict chemical composition control, with carbon content typically maintained between 0.14% and 0.22%, manganese between 0.30% and 0.65%, and minimal phosphorus and sulfur levels to guarantee optimal mechanical properties. These screw rods are available in multiple standard lengths, typically ranging from 200 millimeters to 3000 millimeters, with custom lengths available through the factory's customized service department for specialized engineering requirements. The accompanying disc nuts feature a broad bearing surface that distributes clamping forces evenly across the connected materials, preventing surface deformation and maintaining joint integrity under dynamic loading conditions.

Compliance with international fastener standards is a cornerstone of the manufacturing philosophy at Qiǎnshèng Metal Products, and these 100kN steel screw rods and disc nuts are produced to meet or exceed requirements specified in standards such as GB/T 5782, DIN 975, and ASTM A307. The GB/T standard governs dimensional specifications for hexagon head bolts and screw rods in China, ensuring that these components interface correctly with locally manufactured structural elements and mounting hardware. For international clients, the DIN 975 standard provides assurance that threaded rods meet German industrial requirements for strength, thread pitch, and material quality, which are widely recognized as benchmarks in the global construction industry. ASTM A307 compliance further demonstrates that these fasteners satisfy American Society for Testing and Materials requirements for carbon steel bolts and studs used in general engineering applications. The disc nuts are manufactured according to corresponding standards that specify hardness, flatness, and surface finish characteristics critical for consistent performance in demanding construction environments.

The exceptional load-bearing capacity of these 100kN steel screw rods is achieved through precise heat treatment processes that optimize the crystalline structure of Q235 steel, increasing its yield strength while preserving sufficient ductility to prevent brittle fracture under sudden impact loads. Forged screw rods undergo hot working processes at temperatures between 1100°C and 1250°C, which refines the grain structure and eliminates internal voids or porosity that could weaken the finished component under tension. The forging process aligns the metal grain flow along the contours of the screw rod shape, resulting in superior fatigue resistance compared to machined or cast alternatives, making forged rods the preferred choice for critical structural connections in bridges, high-rise buildings, and industrial facilities. Cast screw rods, while suitable for less demanding applications, offer cost advantages for large-volume projects where the full mechanical properties of forged components are not required, and they still undergo quality inspection to verify load capacity and dimensional accuracy. Surface treatments such as hot-dip galvanizing, black oxide coating, or zinc plating are available to enhance corrosion resistance, extending service life in outdoor or chemically aggressive environments without compromising thread fit or nut engagement.

The disc nut component is equally critical to the overall assembly performance, featuring a carefully calculated diameter-to-thickness ratio that maximizes contact area while minimizing material usage and weight. Precision threading on both the screw rod and disc nut ensures consistent torque-tension relationships during installation, allowing engineers to achieve accurate preload values using standard torque wrenches without specialized calibration equipment. The combination of high-strength Q235 steel construction with optional forged or cast manufacturing processes gives procurement professionals the flexibility to select the optimal balance of strength, cost, and durability for each specific application. Whether securing steel columns to concrete foundations, connecting truss systems in industrial buildings, or anchoring heavy machinery to vibration-dampening mounts, these screw rod and disc nut assemblies deliver reliable performance that meets or exceeds engineering specifications. The factory direct sales model at Qiǎnshèng Metal Products ensures that every component leaving the production facility has been inspected, tested, and certified according to the standards requested by the client, providing complete traceability from raw material sourcing to final product shipment.

Construction engineering projects rely on high-strength fastening systems to transfer loads between structural elements safely and efficiently, and the 100kN Q235 steel screw rod with disc nut is designed specifically to excel in these demanding applications. Steel frame building construction represents one of the largest markets for these components, where they are used to connect beams to columns, secure bracing systems, and anchor roof trusses against wind uplift and seismic forces. In concrete formwork systems, these screw rods serve as tie rods that hold form panels together under the enormous pressure exerted by wet concrete, maintaining precise alignment until the concrete gains sufficient strength to support its own weight. Bridge construction projects utilize these high-strength threaded rods in bearing assemblies, expansion joint connections, and temporary works that require reliable load transfer during both construction and the operational life of the structure. Industrial plant installations, including power generation facilities, chemical processing plants, and manufacturing factories, depend on these fasteners to secure heavy equipment, piping systems, and support structures that must operate reliably for decades under continuous load conditions.

The versatility of the disc nut design makes these assemblies particularly valuable in applications where space constraints or surface geometry prevent the use of standard hexagon nuts and washers. The broad, flat bearing surface of the disc nut distributes clamping forces evenly across slotted or irregular mounting surfaces, reducing the risk of stress concentrations that could initiate cracking in structural steel members or concrete anchors. Infrastructure projects such as tunnel lining installation, retaining wall construction, and port facility development benefit from the corrosion-resistant finishes available on these screw rods, which maintain their mechanical properties even when exposed to groundwater, deicing chemicals, or salt spray environments. The ability to source these components directly from the factory throughHome or explore the complete product range on the Products page streamlines procurement for engineering contractors managing multiple projects across different regions and regulatory jurisdictions.
