Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address critical alignment and fastening challenges in industrial machinery, automation systems, and precision equipment. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, while the black oxide finish adds an extra layer of protection against wear and galling. The Class 5g6g thread fit ensures reliable engagement in metric coarse pitch applications, reducing the risk of cross-threading. The knurled socket head with a 2mm hex drive allows for secure torque application, minimizing stripping in high-vibration environments. With a 12mm shoulder length and tight tolerances, it offers precise locating and pivoting functions, making it ideal for assemblies requiring exact component spacing and rotational control.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with an M4 x 0.7mm coarse thread and Class 5g6g thread fit for precise dimensional accuracy. Shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible manufacturing and usage in global markets.
