Professional Applications & Engineering Value
This M3 metric sealing screw is engineered to address common industrial challenges such as fluid leakage, vibration loosening, and corrosion in demanding applications. Made from 316 stainless steel, it offers excellent resistance to chemicals and moisture, making it suitable for marine, chemical processing, and food equipment. The flat head with undercut profile ensures a countersunk fit that minimizes protrusion and maximizes sealing efficiency when combined with the silicone rubber O-ring. Its fully threaded design and coarse thread pitch facilitate faster installation and reliable performance in high-pressure systems up to 6000 psi, reducing maintenance needs and downtime in industrial fastening scenarios.
Specification Summary & Compliance
This screw adheres to precise Class 6g thread fit and DIN 965 standards for dimensional accuracy, with a thread size of M3 x 0.5mm and length of 20mm. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
