Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical alignment and wear challenges in precision machinery. The 18-8 Stainless Steel base material offers excellent corrosion resistance, while the TiCN coating significantly reduces friction and extends component life in rotating assemblies. The 1" shoulder length with tight tolerances provides a stable bearing surface for gears, pulleys, and linkages, minimizing radial play. With a Class 2A thread fit and coarse UNC threads, it ensures quick installation and reliable holding power in automated systems, conveyor equipment, and packaging machinery where vibration resistance and repeatability are essential.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit with UNC coarse threads (8-32 size) and precise shoulder dimensions (3/16" diameter with -0.002" to 0" tolerance, 1" length with 0" to 0.003" tolerance). Manufactured from 18-8 Stainless Steel with TiCN coating, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards for hazardous substance restrictions.
