Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion-induced failure. The 12mm shoulder length acts as a precise pivot or spacer in assemblies, maintaining accurate positioning in machinery, automotive, and automation systems. Made from 18-8 stainless steel with a black oxide finish, it resists rust and wear in humid or chemically aggressive settings. The coarse M6x1 thread and Class 5g6g fit ensure quick, secure fastening with high clamp force, while the knurled socket head and 4mm hex drive enhance torque transmission, reducing installation time and tool slippage in confined spaces. Ideal for pivots, guides, and rotating components, this screw delivers long-term reliability and reduces maintenance needs.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, with a Metric M6x1 coarse thread and Class 5g6g thread fit for precise dimensional accuracy. The shoulder diameter is 8 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 12 mm with a 0 to 0.25 mm tolerance, ensuring consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and global industrial applications.
