Professional Applications & Engineering Value
This Phillips pan head screw with external-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 provides excellent corrosion resistance for environments exposed to moisture, chemicals, or outdoor conditions. The external-tooth lock washer bites into both the bearing surface and screw head, creating a mechanical lock that maintains clamp load where conventional fasteners might fail. With UNC coarse threads and Class 2A thread fit, installation is streamlined while ensuring reliable engagement in various materials. The fully threaded design offers flexibility in adjustment while the 70,000 psi tensile strength supports heavy-duty applications requiring dependable fastening solutions.
Specification Summary & Compliance
This fastener features 6-32 UNC coarse threads with Class 2A tolerance for precise fit and reliable performance. Manufactured in compliance with ASME B18.13 specifications for dimensional accuracy and quality. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and safety standards. The external-tooth lock washer is constructed from 410 stainless steel with matching passivated finish for consistent corrosion protection throughout the assembly.
