Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and rotational challenges in industrial assemblies. The 1/2" shoulder length provides a stable, unthreaded bearing surface that acts as a pivot, spacer, or axle, preventing component misalignment and reducing wear on moving parts. Made from 18-8 stainless steel with a passivated finish, it offers excellent resistance to oxidation and chemical exposure, making it suitable for machinery, automotive, and electronics applications where corrosion resistance is paramount. The 6-32 UNC coarse thread and Class 2A fit ensure quick assembly and reliable holding power, while the hex socket drive allows for high-torque installation in confined spaces, enhancing efficiency and reducing assembly time in production lines.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent, reliable engagement. The shoulder features precise dimensions: diameter of 5/32" with a tolerance of -0.001" to 0", and length of 1/2" with a tolerance of 0" to 0.002", ensuring exact fit in precision applications. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for use in regulated industries without hazardous substances.
