Professional Applications & Engineering Value
These rounded head Phillips screws with lock washers deliver critical vibration resistance in industrial machinery, electrical enclosures, and automotive assemblies where loosening under dynamic loads poses significant reliability concerns. The combination of 18-8 stainless steel material and passivated finish provides exceptional corrosion resistance for outdoor equipment and chemical processing applications. The external-tooth lock washer bites into both the bearing surface and screw head, creating a mechanical lock that outperforms standard flat washers. With UNC coarse threading and Class 2A fit, these fasteners install quickly while maintaining precise alignment, reducing assembly time and preventing cross-threading damage in production environments.
Specification Summary & Compliance
This 6-32 x 5/16" rounded head screw features UNC coarse threading with Class 2A tolerance for reliable engagement. Manufactured to ASME B18.13 specifications with fully threaded design and pan head profile. The assembly includes matching 410 stainless steel external-tooth lock washer with passivated finish. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global industrial use.
