Professional Applications & Engineering Value

This M5 x 0.8mm metric flat head screw is engineered to solve critical challenges in industrial sealing and fastening. The core of its value lies in the combination of 316 stainless steel for superior corrosion resistance and a Viton® fluoroelastomer O-ring for high-pressure sealing. This design directly addresses common failure points in machinery, enclosures, and fluid systems by preventing leaks of oils, fuels, and chemicals, even under 6,000 psi of pressure. The fully threaded coarse thread design with a Class 6g fit provides excellent grip and vibration resistance, while the undercut flat head ensures a flush fit that minimizes protrusion and snagging. This makes it an indispensable component in industrial applications such as pump housings, valve assemblies, and high-temperature equipment, where reliability and environmental compliance are non-negotiable.
