Professional Applications & Engineering Value

This M5 socket head cap screw is engineered to solve critical sealing and fastening challenges in industrial environments. The 18-8 stainless steel construction offers excellent resistance to corrosion and oxidation, which is vital for machinery exposed to moisture, chemicals, or outdoor conditions. The inclusion of a Buna-N rubber O-ring provides a reliable seal that prevents leakage of oils, coolants, and compressed air in applications such as hydraulic systems, pumps, and compressed air equipment. Its fully threaded metric design with a coarse 0.8 mm pitch ensures quick assembly and a strong hold, reducing installation time while maintaining a secure fit even under high pressure up to 1500 psi. This makes it an indispensable component for engineers requiring a durable, sealing cap screw that performs consistently in demanding industrial applications.
