Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value for industrial applications requiring permanent, vibration-resistant fastening. The 90° cone point creates deep penetration into mating surfaces, preventing slippage in high-torque applications such as shaft collars, gears, and pulleys. The Class 3A UNC thread fit ensures precise engagement with minimal backlash, while the hex drive headless design allows for flush mounting in space-constrained assemblies. Manufactured from alloy steel with Rockwell C45 hardness, this set screw maintains its structural integrity under repeated stress cycles, making it ideal for heavy machinery, automotive components, and industrial equipment where reliability is paramount. The combination of coarse threading and right-hand direction provides quick installation while the black-oxide surface treatment offers additional corrosion protection in challenging environments.

Specification Summary & Compliance

This set screw features precision 3/8"-16 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. The fastener complies with ASME B18.3 specifications (ASTM F912) and meets stringent regulatory requirements including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance. With a total length of 2-1/2 inches and 3/16" hex drive, this headless set screw is manufactured to exacting industrial standards for reliable performance in demanding applications.
