Professional Applications & Engineering Value

This 316 Stainless Steel shoulder screw is engineered to solve critical challenges in precision assembly and machinery. The M6 metric thread with a 1 mm coarse pitch and Class 5g6g fit provides reliable fastening with excellent vibration resistance, reducing the risk of loosening in dynamic systems. The integrated 15 mm shoulder acts as a precise pivot, axle, or spacer, maintaining alignment in rotating assemblies, linkages, and fixturing without the need for additional components. The hex socket drive allows for high-torque installation in confined spaces, while the knurled head enhances grip during manual adjustments. Made from corrosion-resistant 316 stainless steel, it performs reliably in demanding environments such as chemical processing, marine equipment, and food machinery, ensuring long-term integrity and reduced maintenance.
