Professional Applications & Engineering Value

This 10-24 UNC flat head sealing screw delivers critical performance in demanding industrial applications where fluid containment and corrosion resistance are paramount. The 316 Stainless Steel material provides exceptional durability against chemicals, saltwater, and extreme temperatures, while the Buna-N rubber O-ring creates a reliable seal in hydraulic systems, pneumatic equipment, and marine components. The undercut flat head profile with 82° countersink ensures flush mounting without protruding edges, preventing snagging in machinery. With coarse UNC threading and Class 2A fit, installation is streamlined while maintaining secure fastening under vibration, making it ideal for high-pressure sealing in valves, pumps, and industrial enclosures where leak prevention is critical.
