- Environmental compliance assurance with RoHS 3 and REACH standards for global manufacturing applications
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional engineering value in demanding industrial environments where vibration resistance and permanent locking are critical. The nylon patch thread locking technology prevents loosening under extreme temperature fluctuations (-50°F to 250°F), making it ideal for precision machinery, automotive assemblies, and electronic enclosures. The cup tip design provides concentrated contact pressure that minimizes damage to shaft surfaces while maintaining superior holding power. Combined with Class 3A UNC coarse threads and Rockwell C45 hardness, this hex drive set screw ensures reliable performance in high-stress applications where repeated adjustments aren't feasible, offering engineers a maintenance-free fastening solution that withstands rigorous operational conditions.
Specification Summary & Compliance
This 6-32 UNC thread set screw features precise Class 3A thread fit with coarse thread spacing, manufactured to ASME B18.3 specifications where applicable per ASTM F912. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
