Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in precision machinery, automotive assemblies, and industrial equipment where vibration resistance and reliable positioning are critical. The 90° cone point effectively bites into mating surfaces, preventing rotational movement in shafts, collars, and gears. The Class 3A UNF fine threads maintain tight tolerances for precise adjustment applications, while the Rockwell C45 hardness ensures the fastener withstands repeated adjustments without thread wear. The headless hex design with 1/8" drive is ideal for space-constrained assemblies requiring flush mounting, making these set screws perfect for permanent installations in high-stress environments.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications and ASTM F912 standards, this set screw features precise 1/4"-28 UNF Class 3A threads with fine spacing for superior fit. The 1 1/2" length and 0.25" thread diameter provide optimal engagement depth. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and international market suitability for industrial fastener applications.
