Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and secure fastening. The Class 3A UNF fine threads provide superior resistance to vibrational loosening in machinery, automotive assemblies, and precision equipment. The Rockwell C45 hardness rating ensures the fastener maintains its structural integrity under repeated stress cycles, while the headless design with 1/8" hex drive enables installation in confined spaces where traditional fasteners cannot operate. The black-oxide surface treatment offers essential corrosion protection in environments exposed to moisture, chemicals, or temperature variations, making these set screws ideal for manufacturing equipment, power transmission systems, and precision instrumentation where reliability cannot be compromised.

Specification Summary & Compliance

This precision fastener features 1/4"-28 UNF Class 3A fine threads with right-hand direction and flat tip configuration, manufactured to exacting ASME B18.3 standards for dimensional accuracy and performance consistency. The 7/16" length and 1/8" hex drive provide optimal engagement and torque transmission. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while maintaining the highest quality standards for professional applications.
