Professional Applications & Engineering Value

This precision-engineered 10-32 UNF set screw delivers exceptional performance in industrial power transmission systems, machinery assemblies, and precision equipment where vibration resistance and secure positioning are critical. The black oxide alloy steel construction provides superior corrosion protection while maintaining the high strength needed for heavy-duty applications. The extended tip design ensures deeper penetration into shaft materials, creating a permanent locking effect that prevents component slippage under dynamic loads. With fine thread spacing and Class 3A thread fit, this headless hex drive screw offers precise adjustment capabilities and reliable performance in automotive, aerospace, and manufacturing applications where space constraints demand compact, high-performance fastening solutions.

Specification Summary & Compliance

This set screw features precision Class 3A thread fit with 10-32 UNF fine threads and right-hand thread direction, manufactured to exacting ASME B18.3 standards. The extended tip design maintains tight dimensional tolerances with tip diameter of 0.127" (-0.007" to 0 tolerance) and tip length of 0.049" (-0.005" to 0 tolerance). The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
