Professional Applications & Engineering Value
This zinc plated alloy steel set screw delivers critical performance in demanding industrial settings where vibration resistance and corrosion protection are paramount. The headless hex drive design allows flush mounting in confined spaces while maintaining high torque capability. With Class 3A thread fit and UNC coarse threading, it provides superior clamping force for machinery components, pulleys, and collars that experience dynamic loads. The Rockwell C45 hardness ensures the cup tip maintains its form under repeated adjustments, preventing damage to shaft surfaces. Engineered to ASME B18.3 specifications, this 5/8" length set screw offers reliable positioning in automotive, manufacturing, and heavy equipment applications where precision fastening is non-negotiable.
Specification Summary & Compliance
This set screw features 3/8"-16 UNC coarse threads with Class 3A thread fit for precision tolerance. Manufactured to ASME B18.3 specifications where identified per ASTM F912. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. Dimensions include 5/8" length with 3/16" hex drive and right-hand thread direction.
