Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in machinery. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for demanding environments like automotive assemblies, electronic enclosures, and precision instruments. The 4mm shoulder acts as a precise pivot or spacer, reducing stress on threaded sections and ensuring accurate part positioning. With a hex socket drive and knurled head texture, it allows for secure tool engagement and manual adjustments, minimizing slippage during installation. The Class 5g6g thread fit and coarse M5x0.8 thread enable fast, reliable fastening in high-vibration settings, enhancing overall equipment reliability and reducing maintenance downtime.
Specification Summary & Compliance
This shoulder screw features a metric thread with Class 5g6g tolerance for precise fit, a shoulder diameter tolerance of -0.04 to -0.01 mm, and shoulder length tolerance of 0 to 0.25 mm. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence in industrial applications.
