Professional Applications & Engineering Value

This M4 flat head sealing screw is engineered to address critical challenges in industrial applications where fluid or gas containment is essential. The combination of 18-8 stainless steel and a passivated finish provides excellent resistance to corrosion and wear, extending service life in moist or chemical-exposed settings. The integrated Viton® fluoroelastomer O-ring ensures a reliable seal against high pressure (up to 6000 psi) and temperature fluctuations, preventing leaks in hydraulic systems, automotive components, or HVAC equipment. Its fully threaded metric coarse thread with Class 6g fit facilitates quick assembly and consistent performance, while the Phillips drive and undercut flat head design enable efficient, low-profile installations. Ideal for OEMs and maintenance teams, this screw minimizes downtime and enhances operational safety in high-pressure sealing scenarios.
