Professional Applications & Engineering Value
This 5/16"-18 UNC set screw delivers critical engineering solutions for industrial applications requiring secure component positioning. The black oxide alloy steel construction combined with Class 3A thread fit addresses common vibration-induced loosening problems in machinery, power transmission systems, and precision equipment. The extended tip design provides superior biting action into shafts and collars, preventing rotational slippage under high torque conditions. With coarse thread spacing and right-hand thread direction, installation efficiency is maximized while maintaining the integrity of critical assemblies. The 2" length offers versatile application across various industrial settings where reliable, long-term fastening is paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit tolerance for precision engagement. Features UNC coarse threads with 5/16"-18 sizing and extended tip dimensions (0.203" diameter, 0.082" length) held to tight tolerances. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The alloy steel material achieves Rockwell C45 hardness for optimal strength-to-weight performance.
