What are Metric Serrated Flanged Hexagon Sealing Nuts?

A high-tech variant of our Serrated Flange Nuts, this Sealing Fastener provides a dependable solution to prevent equipment being exposed to toxins and contaminants as a result of leaks within an assembly.

The Serrated Flange of these Sealing Nuts also aids with resistance to self loosening, making this fastener an ideal choice for industrial applications requiring an air-tight seal, even in extreme conditions where vibration is common.

Manufactured by ZAGO to a unique engineering process, Serrated Flange Sealing Nuts feature Military Standard O Ring technology. When installed to the required torque, these O Ring Nuts help ensure that equipment is protected from hazardous substances, with a leak proof seal preventing damage to vulnerable parts, such as tanks, pumps and motors.

Reusable and supplied ready to use with no assembly required, this fastener is fitted with a resilient rubber O Ring and provides a more cost effective and user friendly self-sealing solution over using a conventional Serrated Flange Nut with a separate O Ring.

Accu can supply a variant without a flange in our range of Metric Sealing Hex Nuts.

A bolt variant is also available in our standard range, please see our Hexagon Sealing Bolts for further information and availability.
