Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical alignment and corrosion challenges in precision industrial applications. The 1" shoulder length with precise tolerances ensures accurate positioning of moving parts in machinery, jigs, and assemblies, reducing wear and misalignment. The UNC coarse thread and Class 2A fit facilitate quick assembly while maintaining secure fastening under dynamic loads. The passivated finish on the 316 stainless steel provides enhanced resistance to chemicals, moisture, and oxidation, making it ideal for demanding environments like marine, chemical processing, and food equipment. Combined with a hex socket head, it offers reliable installation in confined spaces, ensuring operational integrity and reduced maintenance.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder features a diameter of 3/16" with a tolerance of -0.001" to 0" and a length of 1" with a tolerance of 0" to 0.002" for precise assembly. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for regulated industrial and international markets.
