Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial machinery, automation systems, and precision equipment. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, while the black oxide finish adds an extra layer of protection against wear and galling. The 10mm shoulder diameter with precise tolerances ensures accurate component positioning, reducing misalignment and vibration in assemblies. With a coarse metric thread and hex socket drive, it allows for efficient installation and removal in high-volume production environments. Ideal for use in pivots, spacers, and rotating mechanisms, this fastener enhances operational reliability and extends service life in demanding applications.

Specification Summary & Compliance

This shoulder screw features M6x1mm coarse threads with a Class 5g6g thread fit for consistent engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional accuracy. Manufactured in compliance with ISO 7379 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe and sustainable use in various industrial sectors.
