Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and mounting challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in demanding conditions. The low socket head design allows for compact assemblies where clearance is limited, while the precise shoulder fit ensures accurate positioning of moving parts like gears, pulleys, or linkages. With its UNC coarse threads and Class 2A fit, it offers reliable fastening that withstands vibrations, reducing maintenance needs and downtime in machinery, automation systems, and electronic enclosures.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent performance. The shoulder features precise dimensions: 5/32" diameter (-0.001" to 0" tolerance) and 1/4" length (0" to 0.002" tolerance). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances for safe industrial use.
