Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in demanding industrial applications where vibration resistance and precise positioning are critical. The Class 3A thread fit with 3/8"-24 UNF fine threads provides superior clamping force and prevents loosening in machinery, automotive components, and precision equipment. The 118° cone point angle bites deeply into shafts and collars, creating permanent positioning without damaging the mating surface. Engineered with Rockwell C45 hardness, these headless set screws maintain their structural integrity under high stress and repeated adjustments, making them ideal for permanent assemblies in manufacturing, robotics, and power transmission systems where reliability cannot be compromised.
Specification Summary & Compliance
This precision set screw features 3/8"-24 UNF fine threads with Class 3A thread fit for superior dimensional accuracy. Manufactured from alloy steel with black-oxide surface treatment and Rockwell C45 hardness. The 1/4" length and cone point design comply with ASME B18.3 specifications and ASTM F912 standards. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use worldwide.
