Professional Applications & Engineering Value

These Phillips pan head screws with external-tooth lock washers provide engineered solutions for vibration-prone applications where secure fastening is critical. The combination of 18-8 stainless steel material and passivated finish offers exceptional corrosion resistance, making them ideal for industrial equipment, machinery, and outdoor applications exposed to moisture and chemicals. The external-tooth lock washer bites into both the screw head and mounting surface, creating positive locking action that prevents back-off in high-vibration environments. With UNC coarse threading and Class 2A thread fit, these screws ensure quick installation and reliable performance in metal assemblies, electronic enclosures, and mechanical systems where vibration resistance and corrosion protection are paramount.

Specification Summary & Compliance

This fastener features precision 6-32 UNC coarse threading with Class 2A thread fit for consistent engagement and reliable performance. Manufactured to meet ASME B18.13 specifications for dimensional accuracy and mechanical properties. The assembly is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The combination of 18-8 stainless steel screw and 410 stainless steel lock washer, both with passivated finish, provides uniform corrosion protection throughout the fastener assembly.
