Professional Applications & Engineering Value

This 3/8"-16 UNC hex headless set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and precise positioning are critical. The black-oxide alloy steel construction combined with the green nylon 6/6 plastic tip creates an optimal solution for preventing component slippage in machinery, automotive assemblies, and precision equipment. The Class 3A thread fit ensures tight tolerances for secure fastening, while the coarse UNC thread facilitates quick installation and removal. The headless design allows for flush mounting in confined spaces, making it ideal for shaft collars, gears, and pulleys where protrusions are unacceptable. With its temperature-resistant nylon tip maintaining integrity across extreme conditions, this set screw provides reliable performance in both high-vibration environments and temperature-fluctuating applications.

Specification Summary & Compliance

This set screw features precise 3/8"-16 UNC coarse threads with Class 3A fit for superior thread engagement and dimensional accuracy. The fastener meets ASME B18.3 manufacturing specifications ensuring consistent quality and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and material safety. The assembly maintains exacting standards with 0.375" thread diameter, 1/4" length, and 3/16" hex drive size for reliable installation across industrial applications.
