Professional Applications & Engineering Value
This precision shoulder screw solves critical alignment challenges in machinery assembly, pivot mechanisms, and precision instruments. The 316 stainless steel construction with passivated finish provides exceptional resistance to chemicals, saltwater, and industrial atmospheres, making it ideal for marine equipment, food processing machinery, and chemical processing applications. The exact 1/2" shoulder length with tight manufacturing tolerances ensures precise spacing between components, eliminating misalignment issues that can cause premature wear or operational failure. The 6-32 UNC coarse thread with Class 2A fit offers reliable engagement in both metallic and non-metallic materials, while the socket head design with hex drive allows for compact installation in space-constrained applications where traditional bolt heads won't fit.
Specification Summary & Compliance
This shoulder screw features 6-32 UNC coarse threads with Class 2A thread fit for standard industrial applications. The shoulder diameter maintains precise tolerance from -0.001" to 0", while the critical shoulder length is controlled within 0" to 0.002" tolerance. Manufactured from 316 stainless steel with passivated finish, the screw delivers 70,000 psi tensile strength and Rockwell B79 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial markets and regulated applications.
