Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component slippage. The alloy steel construction, combined with a Black Oxide finish, provides resistance to corrosion and wear, extending service life in harsh industrial settings. The precisely machined shoulder—with a diameter of 3/16" and length of 1-3/4"—ensures accurate alignment of parts like gears, pulleys, and linkages, reducing downtime and maintenance costs. Its coarse UNC threads and Class 2A fit facilitate quick assembly while maintaining secure fastening, making it ideal for automation equipment, automotive assemblies, and heavy-duty manufacturing systems where reliability is critical.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder diameter tolerance is maintained between -0.001" to 0", and shoulder length tolerance from 0" to 0.002" to ensure precise assembly. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial applications without hazardous substances.
