Professional Applications & Engineering Value
These zinc-plated steel rounded truss head screws deliver exceptional engineering value across industrial applications where vibration resistance and corrosion protection are critical. The combination of 60,000 psi tensile strength and Rockwell B69 hardness ensures reliable performance in heavy-duty assemblies, while the wide truss head profile provides superior clamping force distribution that prevents damage to softer materials. The 6-32 UNC coarse threading offers excellent grip in various substrates, and the zinc plating creates a protective barrier against oxidation and environmental factors. These fully threaded screws are particularly valuable in electrical enclosures, machinery guards, and automotive components where corrosion resistance and structural integrity are paramount for long-term operational safety.
Specification Summary & Compliance
This 6-32 UNC screw features precise dimensional specifications including 3/8" length, 0.321" head diameter, and Class 2A thread fit tolerance for consistent performance. Manufacturing complies with ASME B18.6.3 standards for dimensional accuracy and quality assurance. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and safety for industrial applications worldwide.
