Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and load-bearing challenges in industrial applications. The unthreaded shoulder acts as a precise pivot, bearing surface, or axle, eliminating the need for separate bushings and reducing component count. Made from alloy steel and treated with a black oxide finish, it offers excellent resistance to corrosion and abrasion, which is vital for machinery operating in harsh conditions. The coarse metric thread (M5x0.8) and Class 5g6g tolerance ensure quick assembly and a secure fit, even in materials prone to stripping. Its high tensile strength and knurled socket head make it a reliable choice for precision assemblies in automation, automotive jigs, and conveyor systems, where failure is not an option.

Specification Summary & Compliance

This metric shoulder screw features an M5x0.8 thread with a Class 5g6g thread fit, ensuring dimensional accuracy per ISO standards. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, guaranteeing precise location and fit. It is manufactured from alloy steel to a hardness of Rockwell C32, with a tensile strength of 140,000 psi. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial markets.
