Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, automated systems, and fixturing applications. The 316 stainless steel material provides excellent resistance to chemicals and moisture, preventing failure in corrosive settings. The integral 8mm shoulder acts as a precise locating dowel, maintaining accurate part positioning and absorbing radial loads, which minimizes misalignment and component wear. Combined with the black oxide finish for added corrosion protection and the hex socket drive for secure installation in confined spaces, this screw delivers reliable performance and reduces maintenance needs in demanding industrial environments.

Specification Summary & Compliance

This metric shoulder screw features an M5x0.8 coarse thread with a Class 5g6g thread fit for standard tolerance applications.
