Professional Applications & Engineering Value

This M6 shoulder screw is engineered from alloy steel to address critical alignment and pivot requirements in machinery, automation, and precision equipment. The 75mm shoulder length provides a stable bearing surface, preventing axial movement and reducing stress on threaded sections. With a black oxide finish, it offers enhanced corrosion resistance in humid or mildly corrosive settings, such as assembly jigs, rotating shafts, and conveyor systems. The coarse pitch metric thread and Class 5g6g thread fit ensure rapid installation and consistent clamping, minimizing assembly time while maintaining high tensile strength. Ideal for applications demanding exact positioning and durability, this fastener delivers long-term reliability in industrial and manufacturing environments.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 for dimensional accuracy, featuring an M6x1mm coarse pitch thread with Class 5g6g thread fit. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise fit. It is manufactured from alloy steel with a hardness of Rockwell C32 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
