Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in demanding industrial applications where vibration resistance and corrosion protection are critical. The Class 3A thread fit maintains precise tolerances for secure fastening in machinery, automotive components, and power transmission systems. Engineered with Rockwell C45 hardness, it withstands heavy rotational forces while the coarse UNC threading ensures rapid assembly in production environments. The headless design with 1/4" hex drive provides reliable torque application in confined spaces, making it ideal for securing collars, gears, and pulleys on shafts where flush mounting is required. The black-oxide finish offers superior protection against rust and oxidation in humid or outdoor conditions.
Specification Summary & Compliance
This set screw features 1/2"-13 UNC coarse threads with Class 3A precision fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications with flat tip configuration and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
