Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 5/16"-18 UNC Rounded Head Truss Screws address critical fastening challenges. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, making them suitable for outdoor equipment, marine hardware, and food processing machinery. The wide truss head offers a larger bearing surface, which minimizes the risk of pull-through in softer materials and distributes clamping force evenly. Combined with a drilled spanner drive, these screws allow for high-torque installation without slippage, ensuring reliable connections in heavy-duty assemblies. Their coarse thread design and full threading enhance grip in various substrates, reducing the need for frequent maintenance and replacements.
Specification Summary & Compliance
This screw features a 5/16"-18 UNC thread with Class 2A fit for standard industrial tolerances and easy assembly. It is manufactured in accordance with ASME B18.6.3 specifications, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable usage in global markets.
