• Full thread coverage along the 16 mm length maximizes grip and distribution of clamping force.

Professional Applications & Engineering Value

This M5 sealing socket head cap screw is engineered to address critical challenges in industrial sealing and fastening. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it ideal for use in moist or chemically aggressive settings such as fluid handling systems, machinery enclosures, and automotive assemblies. The integrated silicone rubber O-ring creates a reliable seal that withstands pressures up to 1500 psi, preventing leaks in hydraulic and pneumatic applications. With a coarse 0.8 mm pitch and Class 6g thread, these screws ensure quick, secure installation while maintaining alignment and reducing the risk of cross-threading. Their fully threaded design and Rockwell B85 hardness contribute to enhanced durability and vibration resistance, providing long-term operational stability in demanding engineering environments.
