Professional Applications & Engineering Value

This 8-32 UNC set screw delivers critical engineering solutions for applications requiring permanent, vibration-resistant fastening. The Black-Oxide Alloy Steel construction combined with Rockwell C45 hardness provides exceptional strength against shear forces and environmental degradation. The integrated nylon patch thread locker eliminates the need for additional locking compounds, maintaining secure connections in machinery, automotive assemblies, and precision equipment exposed to temperature fluctuations from -70° to 250°F. The headless design with flat tip ensures maximum contact pressure for superior torque transmission and positioning accuracy in collars, gears, and pulleys where space constraints prohibit protruding fastener heads.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications and ASTM F912 standards, this set screw features precise Class 3A thread fit with UNC 8-32 coarse threading and right-hand orientation. 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. Dimensional accuracy includes 3/8" length, 5/64" hex drive, and 0.164" thread diameter for consistent performance in assembly operations.
