Professional Applications & Engineering Value
This 8-32 x 3/4" rounded head screw is engineered to solve critical fastening challenges in industrial settings. The combination of 18-8 stainless steel and a passivated finish provides exceptional resistance to corrosion and oxidation, making it suitable for outdoor, marine, or chemical-exposed applications. The integrated spring lock washer, made from 410 stainless steel, effectively counters vibration-induced loosening, a common failure point in machinery, automotive, and electrical enclosures. Its UNC coarse threads and Class 2A thread fit facilitate quick, reliable assembly, reducing installation time and labor costs. The Phillips drive ensures widespread tool compatibility, while the pan head design offers a low-profile, secure fit. Ideal for securing components in assemblies that experience constant motion or thermal cycling, this screw delivers long-term reliability and reduces maintenance needs.
Specification Summary & Compliance
This screw features a UNC 8-32 thread with Class 2A dimensional accuracy and coarse pitch for robust engagement. It is fully threaded and meets the ASME B18.13 specification for dimensional consistency. The assembly is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial uses.
