Professional Applications & Engineering Value
These zinc-plated steel flat head screws with 6-32 UNC coarse threading solve critical fastening challenges in industrial assembly where vibration resistance and corrosion protection are paramount. The combination of 60,000 psi tensile strength and Rockwell B70 hardness ensures reliable performance in metal fabrication, machinery enclosures, and electrical panel applications where joint integrity cannot be compromised. The standard 82° countersink angle and flat head profile create seamless surface transitions while the Phillips #2 drive enables rapid installation in high-volume production environments. Engineered to prevent loosening under dynamic loads, these fully threaded screws maintain consistent clamping force throughout their entire engagement length.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for precise dimensional accuracy. The 6-32 UNC coarse thread configuration ensures compatibility with standard mating components. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these screws suitable for global industrial supply chains. The zinc-plated steel construction meets industry standards for corrosion resistance while maintaining the specified mechanical properties.
