• Broad compatibility with UNC coarse threading for quick assembly in various applications
• Regulatory compliance meeting ASME B18.3 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This 8-32 UNC set screw delivers exceptional engineering value through its specialized 18-8 stainless steel composition and cone point design. The 90° cone point angle creates concentrated pressure points that prevent shaft slippage in pulleys, gears, and collars, solving common rotational loosening issues in machinery. The headless configuration allows flush mounting in confined spaces where protruding fasteners would interfere with moving components. With Rockwell B80 hardness, it maintains structural integrity under repetitive stress and vibration, making it ideal for industrial applications requiring permanent positioning of components on shafts. The coarse UNC threading ensures quick installation while the Class 3A thread fit provides precise tolerance control for consistent performance in manufacturing equipment, automotive assemblies, and precision instruments.

Specification Summary & Compliance

This set screw features precise 8-32 UNC coarse threading with Class 3A thread fit for superior dimensional accuracy. Manufacturing complies with ASME B18.3 specifications ensuring consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Additional specifications include right-hand thread direction, 0.164" thread diameter, and 3/4" length for standardized integration into various assembly requirements.
