Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges such as component misalignment and fastener failure under stress. Made from alloy steel and finished with zinc plating, it resists corrosion in demanding environments like machinery, automotive assemblies, and precision equipment. The shoulder design acts as a precise pivot or spacer, maintaining accurate alignment in rotating parts or linkages, while the coarse metric thread (M5x0.8) ensures quick, secure fastening even in softer materials. Its low-profile socket head minimizes protrusion, making it ideal for compact designs. By integrating DIN 923 standards, this screw delivers consistent quality, reducing downtime and maintenance costs in B2B applications such as conveyor systems, robotics, and industrial fixtures.

Specification Summary & Compliance

This shoulder screw features precise dimensions, including a shoulder diameter of 7 mm (tolerance: -0.036 mm to 0 mm) and shoulder length of 5 mm (tolerance: 0.07 mm to 0.15 mm), ensuring tight fits for reliable performance. The thread fit is Class 6g, adhering to standard metric tolerances for consistent engagement. It complies with DIN 923 for mechanical properties, RoHS 3 (2015/863/EU) for restricted substances, and REACH (EC 1907/2006) for chemical safety, meeting essential industrial and environmental regulations.
