Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive, and electronics where exposure to moisture or cleaning agents is frequent. The socket head with 3mm hex drive allows for secure tightening in confined spaces, while the 6mm shoulder diameter ensures precise component positioning, reducing wear on moving parts. With a coarse thread pitch of 0.7mm and Class 5g6g thread fit, it offers reliable fastening in high-vibration environments, enhancing assembly efficiency and product lifespan in demanding settings like robotics, conveyor systems, and precision instruments.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with a thread size of M4 x 0.7mm and thread length of 10mm. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental standards for industrial use.
