- High-strength durability from alloy steel with Rockwell C45 hardness, maintaining integrity under heavy loads
- Secure installation control via 5/64" hex drive and cup tip design, preventing component slippage during tightening
- Optimized for coarse-thread applications with UNC 8-32 threading, enabling rapid assembly in softer materials
- Space-saving headless construction allowing flush mounting where clearance is limited
- Full regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global supply chain integration
Professional Applications & Engineering Value
Engineered for precision locking in industrial machinery, automotive components, and electrical enclosures, this 8-32 UNC set screw delivers exceptional performance where vibration resistance matters most. The black-oxide alloy steel construction provides superior corrosion protection while maintaining Rockwell C45 hardness for repeated adjustment cycles without thread deformation. The cup tip design creates concentrated contact pressure for secure shaft positioning, while the Class 3A thread fit ensures consistent clamping force in right-hand threaded applications. Ideal for permanent fastening in pulleys, gears, and collars where coarse UNC threads prevent loosening under dynamic loads.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit tolerances for precision engagement. Features 8-32 UNC coarse threads with 0.164" diameter and 1/2" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in international markets. Right-hand thread direction with 5/64" hex drive provides standardized installation across industrial applications.
