Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical vibration resistance in demanding industrial applications where loosening can cause equipment failure. The nylon patch thread locker provides permanent locking without compromising disassembly capability, while the Class 3A UNC coarse threads ensure rapid installation and superior clamping force in machinery, automotive components, and power transmission systems. The headless hex drive design allows for flush mounting in pulleys, gears, and collars where protruding fasteners are impractical. With Rockwell C45 hardness and corrosion-resistant black-oxide finish, this set screw maintains integrity in high-stress environments from manufacturing equipment to agricultural machinery.
Specification Summary & Compliance
This set screw features precise 3/8"-16 UNC Class 3A threads with coarse spacing for optimal engagement in softer materials. Manufactured to ASME B18.3 standards and ASTM F912 specifications, it ensures dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict material restrictions.
