Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw is engineered to address critical challenges in industrial settings, such as component slippage and corrosion-induced failure. The Class 3A thread fit and UNF fine threads provide exceptional clamping force and vibration resistance, making it ideal for securing shafts, collars, and gears in machinery, automotive systems, and heavy equipment. The headless hex drive design allows for flush mounting in confined spaces, while the Rockwell C45 hardness ensures the screw maintains integrity under repetitive stress. By combining precise thread specifications with robust material properties, this set screw minimizes maintenance downtime and enhances the reliability of high-demand assemblies.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit tolerances for precise engagement, with 5/8"-18 UNF fine threads and a right-hand direction. Manufactured in compliance with ASME B18.3 specifications, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in global markets.
