Professional Applications & Engineering Value
This rounded head Phillips screw with internal-tooth lock washer addresses critical vibration-induced loosening challenges in industrial equipment, machinery, and automotive assemblies. The combination of 18-8 stainless steel material and passivated finish delivers exceptional corrosion resistance for harsh environments, while the 410 stainless steel lock washer creates permanent tension that maintains clamp force despite continuous vibration. The UNC coarse thread spacing and Class 2A thread fit ensure rapid installation with consistent engagement, reducing assembly time while providing reliable performance in applications where vibration resistance and corrosion protection are paramount. The integrated locking system eliminates the need for separate washers, streamlining inventory and installation processes.
Specification Summary & Compliance
This fastener features UNC coarse threads with Class 2A fit for precise dimensional accuracy and reliable engagement. Manufactured to ASME B18.13 specifications with fully threaded 8-32 configuration and right-hand thread direction. The assembly complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications. The pan-style rounded head profile with No. 2 Phillips drive provides optimal torque transmission during installation.
