Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial and mechanical assemblies. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to corrosion and wear, extending service life in humid or chemically exposed environments. The precise shoulder fit with controlled tolerances allows for accurate component positioning, reducing misalignment and wear in rotating parts like gears, pulleys, and linkages. Its hex socket low head design facilitates installation in confined spaces while maintaining a sleek profile. With a coarse thread and Class 6g thread fit, it ensures fast, secure fastening that withstands vibrations, making it a reliable choice for automation equipment, machinery, and precision instruments.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M5x0.8 coarse thread and Class 6g thread fit for dimensional accuracy. The shoulder features a diameter of 6 mm (tolerance: -0.025 to 0 mm) and length of 30 mm (tolerance: 0 to 0.05 mm) to ensure precise shoulder fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and suitable for global industrial applications.
