Professional Applications & Engineering Value
This 3/8"-16 UNC set screw delivers critical engineering solutions where permanent positioning is required. The 18-8 stainless steel composition provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. Its hex headless design allows flush mounting in confined spaces while the cup tip concentrates clamping force without damaging shaft surfaces. The Class 3A thread fit ensures precise engagement with mating components, preventing backlash in precision assemblies. Particularly valuable in power transmission systems, the serrations create positive locking action that resists vibration-induced loosening in motors, gears, and pulleys. These features make it ideal for industrial set screw applications requiring reliable, maintenance-free performance.
Specification Summary & Compliance
Manufactured to exacting standards with 3/8"-16 UNC coarse threads and Class 3A thread fit for superior dimensional accuracy. Full compliance with ASME B18.3 specifications ensures interchangeability and reliable performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions. The right-hand thread direction and 3/4" length provide standardized installation across industrial applications.
