Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address common industrial challenges such as misalignment and corrosion in precision machinery. Constructed from 316 Stainless Steel with a Black Oxide finish, it resists oxidation and chemical exposure, extending service life in demanding settings like automotive, electronics, and marine equipment. The knurled socket head and hex drive allow for easy torque application, minimizing tool slippage during assembly. With a Class 5g6g thread fit and precise shoulder dimensions, it ensures stable positioning in linkages, bearings, and pivots, reducing wear and maintenance costs. Ideal for applications requiring high tensile strength and reliable performance, this screw supports efficient, long-term operations in industrial shoulder screw uses.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with an M3x0.5mm coarse thread and Class 5g6g thread fit for precise tolerance. Key dimensions include a shoulder diameter of 5 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 8 mm (tolerance: 0 to 0.25 mm), ensuring accurate fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety for industrial applications.
