Professional Applications & Engineering Value

This M4 hex head sealing screw delivers critical performance where fluid containment and pressure integrity are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for harsh environments, while the integrated silicone rubber O-ring creates a reliable seal against leaks, dust, and moisture ingress. Engineered with Class 6g thread fit and coarse metric threading, it ensures secure fastening in high-vibration applications across hydraulic systems, pneumatic equipment, and industrial machinery. The combination of 80,000 psi tensile strength and 20,000 psi pressure rating makes it ideal for critical sealing applications where failure is not an option.
