Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common industrial challenges such as component misalignment and vibration-induced loosening. Made from alloy steel with a black oxide finish, it offers high Rockwell C32 hardness and resilience in harsh conditions. The nylon pellet locking mechanism provides reliable retention from -50° to 250° F, ideal for machinery, automotive, and precision equipment where thermal fluctuations occur. The metric coarse thread and precise shoulder diameter tolerance (-0.049 to -0.01 mm) ensure stable positioning in industrial fasteners, reducing maintenance needs and enhancing operational efficiency.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards with a Class 5g6g thread fit for consistent performance. Dimensions include M6x1 mm thread size, 10 mm shoulder length with 0 to 0.25 mm tolerance, and 8 mm shoulder diameter. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting environmental and safety regulations for global industrial use.
