Phillips Flat Head Seal Screws

ZAGO Phillips Flat Head Seal Screws deliver reliable environmental sealing without additional components. Designed to provide flush fastening in countersunk holes, these screws include an integrated elastomeric O-ring that forms a continuous, 360-degree seal when torqued, blocking fluids, gases and particulates from entering or escaping.

This unified design eliminates the need for secondary washers, gaskets, and sealants, reducing assembly time, lowering total part count, and improving long-term reliability.

Built to perform under pressure and extreme temperatures, ZAGO Phillips Flat Head Seal Screws are proven to deliver in high-stakes applications like machinery and assemblies, where non-snagging surfaces are essential.

All components are fully customizable (see detail below) and engineered-to-order to ensure optimal performance. ZAGO’s team of US-based engineers is available to share their expertise and help make the best choice for your application.
