Professional Applications & Engineering Value

This M4 flat head Phillips screw is engineered to address common challenges in industrial sealing applications, such as fluid containment and pressure management. The combination of 18-8 stainless steel and a passivated finish provides robust resistance to corrosion, extending service life in demanding environments like chemical processing, automotive assemblies, and outdoor machinery. The Buna-N rubber O-ring is critical for creating a tight seal, preventing leaks even under high-pressure conditions up to 6000 psi. Its fully threaded design with a Class 6g fit ensures strong holding power and ease of installation in pre-tapped holes or through materials, while the undercut flat head allows for a flush finish, reducing protrusion and improving safety. Ideal for use in pneumatic systems, hydraulic units, and electronic enclosures, this screw offers reliable performance where sealing integrity is paramount.
