Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The black-oxide alloy steel construction provides excellent corrosion protection while maintaining the Rockwell C45 hardness needed for high-stress environments. The serrations locking mechanism creates multiple biting edges that dig into shaft materials, preventing slippage in motors, gears, and pulleys. The headless design with 5/64" hex drive allows installation in space-constrained applications while the cup tip ensures maximum surface contact for superior torque transmission. These precision set screws are engineered to maintain alignment in machinery, automotive components, and manufacturing equipment where reliable fastening is non-negotiable.
Specification Summary & Compliance
This set screw features 8-32 UNC coarse threads with Class 3A thread fit for precision tolerance and reliable engagement. Manufacturing complies with ASME B18.3 specifications ensuring dimensional accuracy and performance consistency. 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 with strict material restrictions.
