Professional Applications & Engineering Value
These zinc-plated alloy steel flat head screws deliver critical performance advantages for industrial and construction applications where corrosion resistance and mechanical integrity are paramount. The combination of 130,000 psi tensile strength and Rockwell C39 hardness ensures reliable performance under vibration, shock, and heavy loads. The UNC coarse threading with Class 3A fit provides superior thread engagement in various materials, while the 82° countersink angle creates flush surfaces in assembled components. Particularly valuable in electrical enclosures, machinery assembly, and structural frameworks, these fully threaded fasteners eliminate the need for multiple screw types while maintaining consistent clamping force throughout the entire length.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit for superior tolerance control. Features UNC coarse threading (6-32 size) with right-hand direction and fully threaded 1/2" length. Complies with ASTM F835 specification for mechanical properties and performance requirements. Meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) standards for restricted substances, ensuring safe usage across global markets.
