Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address critical alignment and durability challenges in precision machinery and assembly. The 9/16" shoulder length provides a stable bearing surface for rotating components like gears and pulleys, minimizing wear and maintaining concentricity. The low-profile hex socket drive allows for secure tightening in confined spaces, while the passivated finish enhances corrosion resistance in demanding environments such as automotive, aerospace, and electronic equipment. With its 6-32 UNC coarse thread and Class 2A fit, it ensures quick, reliable fastening that withstands vibrations and dynamic loads, reducing maintenance needs and improving operational efficiency.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. The shoulder features precise tolerances (diameter: -0.001" to 0", length: 0" to 0.002") to ensure accurate alignment. It is manufactured from 18-8 stainless steel with a passivated finish, offering a tensile strength of 70,000 psi and Rockwell B55 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting stringent environmental and safety requirements for industrial use.
