Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in industrial settings where vibration resistance and long-term reliability are paramount. The Class 3A thread fit and coarse UNC threads provide superior clamping force, preventing loosening in machinery, motor assemblies, and power transmission systems. Its headless design and hex drive enable flush mounting in tight spaces, while the oval tip ensures secure contact without marring precision components. Ideal for securing gears, pulleys, and collars on rotating shafts, this 5/16"-18 set screw solves common engineering challenges like misalignment and fatigue failure, backed by Rockwell C45 hardness for sustained performance under stress.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit tolerances per UNC standards, with precise dimensions: 5/16"-18 thread size, 5/8" length, and 5/32" hex drive. Manufacturing complies with ASME B18.3 and ASTM F912 specifications, ensuring consistent quality. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for industrial use.
