Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The 316 Stainless Steel material provides excellent resistance to chemicals and moisture, making it suitable for marine, chemical processing, and food industry applications. The coarse 0.5 mm pitch thread and Class 5g6g fit ensure quick, reliable assembly in high-vibration environments, while the hex socket head and knurled texture facilitate easy installation with standard tools. The precision-machined shoulder acts as a pivot or spacer, reducing friction and extending the lifespan of assemblies in machinery, automation systems, and precision instruments.
Specification Summary & Compliance
This shoulder screw features a metric M3x0.5 coarse thread with Class 5g6g thread fit for standard tolerance. Dimensions include a 6 mm head diameter, 5 mm thread length, and 4 mm shoulder diameter with tight tolerances (e.g., shoulder diameter: -0.072 to -0.01 mm). It is manufactured to high standards, compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it meets environmental and safety regulations for industrial use.
