Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion-induced failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive assemblies, and electronic enclosures exposed to moisture. The hex socket head allows for high torque application in confined spaces, while the precision shoulder acts as a reliable datum for locating parts, reducing assembly errors and improving overall mechanical stability. Its coarse thread pitch ensures quick installation and strong holding power in softer materials or where frequent disassembly is required, delivering consistent performance in demanding industrial shoulder screw applications.

Specification Summary & Compliance

The screw features a metric thread with M5 size and 0.8mm pitch, conforming to Class 5g6g tolerance standards for precise thread fit. The shoulder diameter is manufactured to a tight tolerance of -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring accurate alignment. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in products requiring adherence to strict environmental and safety standards.
