Professional Applications & Engineering Value

This Phillips pan head screw with internal-tooth lock washer addresses critical vibration-induced loosening challenges in industrial equipment, machinery, and electronic enclosures. The combination of 18-8 stainless steel material and passivated finish provides exceptional corrosion resistance for harsh environments, while the integrated lock washer creates permanent spring tension that maintains joint integrity. The fully threaded 6-32 UNC coarse thread design ensures maximum thread engagement and faster installation in production environments. These rounded head screws are particularly valuable in applications where thermal cycling, mechanical vibration, or dynamic loads could compromise standard fasteners, making them ideal for automotive components, industrial controls, and precision equipment assemblies requiring reliable, long-term fastening solutions.

Specification Summary & Compliance

This fastener features precision 6-32 UNC coarse threads with Class 2A fit tolerance for consistent engagement. Manufactured to ASME B18.13 specifications ensuring dimensional accuracy and performance reliability. The assembly meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) environmental standards. The passivated finish on both the 18-8 stainless steel screw and 410 stainless steel lock washer enhances corrosion resistance while maintaining the material's mechanical properties.
