Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical holding power in demanding industrial applications where vibration resistance is paramount. The nylon patch thread locking technology effectively prevents loosening under dynamic loads, making it ideal for machinery, automotive components, and precision equipment assemblies. The Class 3A UNF fine threads provide superior thread engagement and clamping force compared to standard coarse threads, while the cup tip design ensures positive seating on shafts and rotating components. Engineered for industrial set screw applications requiring reliable, permanent fastening solutions, this component maintains integrity across wide temperature ranges from -50°F to 250°F without compromising locking performance.
Specification Summary & Compliance
This set screw features Class 3A thread fit with 3/8"-24 UNF fine threads and complies with ASME B18.3 dimensional standards. The component meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. Manufacturing specifications include ASTM F912 standards, with precise dimensional tolerances maintained throughout production for consistent performance in industrial fastening applications.
