• High mechanical strength with 100,000 psi tensile strength and Rockwell B85 hardness, ensuring long-term fastener integrity under load
• Wide temperature compatibility as the O-ring performs consistently from -80° to 400° F, maintaining seal integrity across extreme thermal cycles
• Precise and reliable threading with Class 6g thread fit and coarse M5 x 0.8 mm pitch, enabling easy installation and secure fastening
• Optimized for high-pressure applications, rated for up to 1500 psi, making it suitable for pressurized systems requiring dependable sealing
• Convenient installation and removal with a standard 4 mm hex socket drive, allowing for efficient assembly in confined spaces

Professional Applications & Engineering Value

This M5 socket head cap screw is engineered to address critical sealing challenges in industrial and fluid handling systems. The integration of a silicone rubber O-ring directly tackles common failure points by providing a resilient seal that maintains integrity under high pressure (up to 1500 psi) and across a broad temperature range (-80° to 400° F). Manufactured from 18-8 Stainless Steel, it offers excellent corrosion resistance, which is vital in environments exposed to moisture, chemicals, or outdoor elements. The fully threaded design and Class 6g thread fit ensure uniform clamping force and vibration resistance, reducing the risk of loosening in dynamic applications. These features make it an indispensable component in pneumatic systems, hydraulic assemblies, compressor units, and processing equipment where preventing leaks is paramount to operational safety and efficiency.
