Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw with a Black Oxide finish and UNC coarse threading is engineered to address critical challenges in precision machinery, automation systems, and industrial equipment. The high tensile strength (70,000 psi) and corrosion-resistant material prevent failure under dynamic loads and in corrosive settings, such as marine or chemical processing. The Class 3A thread fit and precise shoulder dimensions ensure consistent alignment and reduced vibration, making it ideal for pivots, guides, and rotating assemblies. Its knurled socket head and hex drive facilitate quick, secure installation in tight spaces, enhancing assembly efficiency and reliability in demanding industrial applications.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with a Class 3A thread fit for high precision. Key dimensional tolerances include shoulder diameter (-0.004" to -0.002") and length (-0.005" to 0.005"), ensuring consistent performance. Manufactured from 316 stainless steel with a Black Oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting use in regulated and environmentally conscious industries.
