Professional Applications & Engineering Value
These zinc-plated steel truss head screws are engineered to address common industrial challenges such as material fatigue and corrosion in demanding settings. The wide truss head design significantly increases bearing surface area, reducing the risk of pull-through in softer substrates and distributing loads evenly to prevent joint failure. With a tensile strength of 60,000 psi and Rockwell B69 hardness, they withstand high-stress conditions in machinery, automotive assemblies, and electrical enclosures. The UNC coarse thread and fully threaded shank ensure quick, reliable fastening in wood, metal, and plastic, while the slotted drive allows for straightforward manual or automated installation. Ideal for applications requiring durable, compliant fasteners, these screws offer long-term performance without compromising on safety or efficiency.
Specification Summary & Compliance
This screw features precise Class 2A thread fit and UNC coarse spacing for consistent assembly, with dimensions including a 6-32 thread size and 3/4" length. It meets ASME B18.6.3 specifications for dimensional accuracy and performance, and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use worldwide.
