Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision machinery. The alloy steel material, combined with Rockwell C32 hardness, ensures exceptional wear resistance and durability under repetitive stress. The black oxide finish not only enhances corrosion protection but also reduces galling in high-friction applications. With its 8 mm shoulder diameter and tight tolerances, this metric shoulder screw provides exact positioning in assemblies like rotating shafts, linkages, and bearing mounts, eliminating misalignment issues. The coarse thread pitch and Class 5g6g fit facilitate rapid installation while maintaining secure fastening in industrial equipment, automotive systems, and automation technology, ultimately boosting operational reliability and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw adheres to metric thread standards with M6 x 1 mm coarse threads and a Class 5g6g thread fit for precise dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel and REACH (EC 1907/2006) regulations, confirming environmental and safety adherence for industrial use.
