Hexagon Sealing Bolts, manufactured in the USA by ZAGO, are designed to withstand extreme temperatures conditions and atmospheres, whilst forming a complete seal to protect machinery and devices from hazardous substances.
Engineered with a specialised groove on the underside of the bolt head, this fastener is fitted with a captive rubber O Ring and is designed to perform more efficiently than using a conventional Hexagon Bolt with a separate O Ring.
When the Sealing Bolt is tightened, the built-in O Ring forms a permanent hermetic seal to ensure optimal performance of sensitive equipment where oils, gases and liquids are present, preventing internal and external leakages.
Produced to Military Specifications, this type of pre-fitted O Ring Bolt is pressure tested to 1500 psi, making it ideal for applications across a wide range of markets, including Medical Devices, Automotive and Industrial Manufacturing.
Hex Sealing Bolts prevent pollutants from seeping into the housing environment and typically have an unlimited shelf-life, whilst also being reusable. As the captive O Ring is supplied pre-fitted into the purpose built groove within the head of the Bolt, this ensures simple installation with metal-to-metal contact for optimal performance of the 360° seal.
