Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion in precision machinery. The 316 Stainless Steel material offers excellent resistance to chemicals and moisture, making it suitable for medical devices, food processing equipment, and marine applications. Its socket head with knurled texture provides a firm grip for high-torque drives, while the 5mm shoulder diameter acts as a precise pivot or spacer, reducing wear on connected parts. The Class 5g6g thread ensures reliable fastening in metric assemblies, maintaining integrity under dynamic loads. This combination of features delivers long-term reliability, minimizing maintenance and downtime in demanding industrial environments.
Specification Summary & Compliance
This precision shoulder screw adheres to metric thread standards with M3x0.5 coarse 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, ensuring precise fits in assemblies. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted substances and safe for various industrial uses.
