Hex Head Seal Bolts

ZAGO Hex Sealing Bolts are engineered for mission-critical applications where pressure, fluid, gas or contaminants threaten equipment performance. Unlike standard bolts, the ZAGO Hex Head Seal Bolt integrates a resilient, rubber-like O-ring forms a continuous, 360-degree seal when torqued, keeping liquids, gas and contaminants from degrading equipment performance.

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 deliver leak-proof seals that protect sensitive systems even under extreme conditions, ZAGO Hex Head Seal Bolts are used in aerospace and defense equipment applications, marine and offshore systems, robotics, drones, medical devices and more.

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.
