6-lobe Flat Head Seal Screws

ZAGO’s 6-Lobe Flat Head Seal Screws deliver flush-mount sealing power. Each fastener integrates a custom-engineered, chemically resistant rubber O-ring that forms a 360-degree barrier against air, water, oil, and dust upon installation. The flat, countersunk design sits flush with the surface, providing a clean, smooth finish without sacrificing protection. With fewer components, ZAGO’s unified design promotes faster assembly while improving protection from a variety of contaminants.

Ideal for enclosures, panels, and assemblies requiring a flush finish, these screws are designed to withstand pressure, temperature and environmental extremes. ZAGO seal screws are reusable, maintenance-free, and proven in mission-critical applications like aerospace, avionics, EV control housing and robotics, amongst others.

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.

MOQ and lead times may vary based on configuration.
