Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot point challenges in machinery and equipment. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, while the black oxide finish adds an extra layer of protection against wear and galling. The precision 15mm shoulder length and controlled diameter tolerance ensure accurate component positioning, reducing misalignment and vibration in assemblies such as rotating shafts, linkages, and bearing mounts. With its Class 5g6g thread fit and coarse thread pitch, it enables faster installation and reliable performance in high-stress industrial environments, from automotive to manufacturing systems.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for precise dimensional control. It is manufactured in accordance with ISO 7379 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in global markets.
