Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional performance in industrial machinery, automotive assemblies, and precision equipment where vibration resistance and corrosion protection are critical. The Class 3A thread fit maintains tight tolerances in high-stress applications, while the 1/4" hex drive provides secure tool engagement during installation. Engineered with Rockwell C45 hardness, this headless set screw withstands repeated adjustments without compromising structural integrity. The coarse UNC threads ensure rapid installation and disassembly in maintenance operations, making it ideal for production lines and equipment requiring frequent component changes.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications and ASTM F912 standards with Class 3A thread fit precision. Features 1/2"-13 UNC coarse threads with right-hand direction and flat tip configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment provides additional corrosion protection while maintaining dimensional stability across the 3/4" length and 0.5" thread diameter.
