Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common challenges in precision mechanical assemblies, such as misalignment and corrosion-induced failure. The 316 stainless steel construction, combined with a black oxide finish, provides exceptional resistance to corrosive elements, making it suitable for applications in marine, chemical processing, and outdoor equipment. The 130 mm shoulder length with minimal tolerance ensures accurate spacing and rotational stability in linkages, pivots, and bearing mounts, reducing vibration and component wear. Its knurled head and hex drive allow for secure tool engagement, speeding up installation in confined spaces while maintaining torque integrity. By integrating Class 5g6g thread fit and coarse threading, this fastener supports rapid assembly in automated production lines, enhancing efficiency without compromising on the high tensile strength needed for demanding industrial environments.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a Class 5g6g thread fit per metric specifications, ensuring reliable thread engagement. The shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm support high accuracy in assembly. It meets ISO 7379 for dimensional and performance criteria, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various industrial sectors without hazardous substances.
