• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Accurate shoulder dimensions with controlled tolerances for consistent alignment and spacing in precision machinery.

Professional Applications & Engineering Value

This 6-32 UNC thread shoulder screw is engineered to address critical challenges in industrial settings, such as misalignment and corrosion-induced failure. Made from 316 Stainless Steel, it provides exceptional resistance to chemicals, saltwater, and high humidity, making it suitable for marine, chemical processing, and food equipment applications. The socket head hex drive and knurled texture facilitate quick assembly and disassembly, even in confined spaces, while the Class 3A thread fit and precise shoulder dimensions ensure stable positioning in rotating parts, linkages, and bearing supports. By combining high tensile strength and shear strength, it reduces maintenance needs and extends service life in heavy-duty machinery and automation systems.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 3A thread fit for high precision. Dimensions include a thread diameter of 0.138", shoulder diameter of 5/32" (tolerance: -0.004" to -0.002"), and shoulder length of 7/16" (tolerance: -0.005" to 0.005"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances for use in various industrial and export markets.
