Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges such as misalignment and corrosion-induced failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, extending service life in demanding settings like machinery, automotive assemblies, and electronic enclosures. The precision shoulder with controlled diameter and length tolerances acts as a reliable pivot or spacer, reducing wear on moving parts and ensuring accurate alignment in right-hand thread applications. Combined with a coarse thread pitch and socket head design, it offers quick, secure fastening that withstands vibrations, making it a trusted choice for engineers seeking durability and efficiency.

Specification Summary & Compliance

The screw features a metric thread with M5 size, 0.8mm pitch, and Class 5g6g thread fit for consistent dimensional accuracy. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, adhering to standard industrial specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global supply chains.
