• Reliable coarse threading with 6-32 UNC Class 2B thread fit for quick assembly and excellent engagement in various materials
• Versatile partial threading design for applications requiring both precise location and secure fastening
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision equipment. The 3/4" shoulder length provides a stable bearing surface for rotating components like gears, pulleys, and linkages, minimizing wear and maintaining precise positioning. Its 6-32 UNC coarse thread ensures rapid, secure fastening even in materials prone to stripping, while the partially threaded design allows the unthreaded shoulder to act as a pivot or axle. The knurled socket head enhances grip during installation, reducing the risk of tool slippage in high-torque scenarios. Ideal for applications requiring corrosion resistance and high tensile strength—such as conveyor systems, electronic enclosures, and medical devices—this shoulder screw delivers reliable performance under repetitive stress and exposure to moisture or chemicals.

Specification Summary & Compliance

This shoulder screw adheres to Class 2B thread fit standards for consistent engagement and assembly ease. Manufactured to inch system specifications, it features a shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005" for precision alignment. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
