Professional Applications & Engineering Value
This precision shoulder screw solves critical alignment challenges in machinery assembly, where exact component positioning is essential. The 3/16" shoulder diameter with precise fit prevents lateral movement in bearings, gears, and pivoting mechanisms, eliminating play that causes premature wear. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance in manufacturing environments exposed to moisture, chemicals, or outdoor conditions. The low profile socket head design allows installation in tight spaces while maintaining high torque capability. With 70,000 psi tensile strength and UNC coarse threads, these industrial shoulder screws deliver reliable performance in automation equipment, precision instruments, and heavy-duty machinery where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit per UNC standards with precise shoulder diameter tolerance of -0.001" to 0" and shoulder length tolerance of 0" to 0.002". The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. Manufacturing meets industrial standards for 8-32 UNC thread specifications with right-hand thread direction and coarse thread spacing for optimal performance in various industrial applications.
