Professional Applications & Engineering Value

This 8-32 UNC Class 3A set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and secure shaft retention. The 18-8 stainless steel composition provides excellent corrosion resistance, making it suitable for machinery operating in demanding environments where moisture or chemicals are present. The hex headless design with 5/64" drive allows for flush installation in confined spaces while maintaining high torque capability. The coarse UNC threads with Class 3A fit ensure rapid assembly and disassembly while providing superior vibration resistance through the serrations locking feature. The cup tip configuration concentrates clamping force for maximum grip on shafts, pulleys, and collars, preventing slippage in high-torque applications across automotive, manufacturing, and precision equipment sectors.

Specification Summary & Compliance

This high-performance set screw features precision 8-32 UNC coarse threads with Class 3A fit for tight tolerances and reliable performance. Manufacturing complies with ASME B18.3 specifications, ensuring dimensional accuracy and interchangeability. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) regulations for chemical safety. With a 1/2" length and 0.164" thread diameter, the component maintains consistent quality across production batches for industrial applications requiring repeatable performance.
