- Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use
Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions for industrial machinery, automation systems, and precision equipment where vibration resistance and reliable positioning are paramount. The black-oxide alloy steel construction combined with Rockwell C45 hardness addresses common failure points in high-stress applications, preventing loosening under dynamic loads. The flat tip design creates maximum surface contact for superior grip on shafts and collars, while the hex drive enables precise torque control during installation. Ideal for permanent fastening in power transmission components, motor assemblies, and precision manufacturing equipment requiring Class 3A thread fit accuracy.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for superior engagement. Features 8-32 UNC coarse threads with right-hand direction and 1/2" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets. The black-oxide surface treatment provides consistent corrosion protection while maintaining dimensional stability.
