Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional engineering value in precision assemblies where vibration resistance and positional accuracy are critical. The Class 3A UNF fine threads provide superior clamping force distribution, while the green nylon 6/6 plastic tip creates a non-marring, self-locking interface that eliminates the need for additional locking components. Engineered for industrial applications requiring repeated adjustments, the headless design with 5/32" hex drive offers tool accessibility in confined spaces. The combination of Rockwell C28 hardness and controlled thread fit ensures consistent performance in machinery, automotive, and electronic enclosures where fastener reliability directly impacts operational safety.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit for precision UNF fine threads (5/16"-24). Features include 0.313" thread diameter, 3/8" length, and right-hand thread direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The nylon tip maintains dimensional stability across specified temperature ranges while providing consistent anti-vibration performance.
