Professional Applications & Engineering Value
This precision M4 shoulder screw is engineered from 18-8 Stainless Steel to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The 10mm shoulder length provides exact spacing in assemblies like rotating shafts and pivots, while the Class 5g6g thread fit ensures reliable fastening in metric coarse thread applications. The knurled socket head with a 2mm hex drive enhances torque application, preventing stripping in high-vibration environments. Ideal for machinery, automotive, and electronics, it offers high strength and durability, reducing maintenance needs and improving operational efficiency in demanding settings.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with an M4x0.7 thread size and pitch, Class 5g6g thread fit for precise tolerance. Shoulder diameter is 4 mm with a tolerance of -0.04 to -0.01 mm, and shoulder length is 10 mm with a 0 to 0.25 mm tolerance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use.
