Hex Head O-Ring Seal Bolts

SKU: SF08 Categories: ,

Hex Head O-Ring Seal Bolts provide a complete, cost-effective sealing fastener with 360° protection against liquids, gases, and other potentially harmful contaminants.

These components operate the same as normal hex head bolts – installed using a standard spanner or wrench. They are equipped with a strong and sturdy Silicone rubber O-ring which is situated within a groove on the underside of the hexagon shaped head.

The ultra-tight seal is specifically designed to prevent contaminants from entering and prevent matter from escaping. As a result, Hex Head O-Ring Seal Bolts are often used in military and medical applications, high-pressure environments, and those with strict sealing requirements.

This O-ring does not prevent metal to metal contact which ensures a strong and secure fixing. It can be supplied in an extensive range of materials to best suit the intended application or assembly e.g. Nitrile rubber (Buna-N), Viton, Fluorosilicone, EPDM, and many more.

Hex Head O-Ring Seal Bolts and Slotted Hex Head O-Ring Seal Bolts are available to order at Fastenright. Both components can be supplied as a fully threaded set screw, typically to DIN 933 / DIN 933SZ / ISO 4017 / ASME B18.6.3, or as a partially threaded bolt, typically to DIN 931 / ISO 4014 / ASME B18.2.1.

Optional thread locking patches can also be provided to increase vibration resistance and preserve the operational life of the O-ring.

Hex Head O-Ring Seal Bolts are tailor made to meet your requirements – manufactured to order in a wide range of sizes, materials, and finishes. Minimum order quantities apply.

We supply a selection of Sealing Fasteners here at Fastenright, including a range screws, bolts, nuts, rivets and security fasteners.
