Rubber Nut Inserts for Materials up to 39.00mm Thick

The RFOR Round Flat Head Open End Rubber Nut Insert is designed to provide a secure, vibration-resistant threaded fixing solution for materials up to 39.00mm thick. Featuring a brass threaded insert moulded into a durable neoprene or EPDM rubber body, these rubber nuts offer a reliable fastening method where traditional rivetnuts or threaded inserts may not be suitable.

When tightened, the rubber body expands behind the panel, creating a strong blind fixing while helping to absorb vibration, reduce noise, and provide resistance to moisture and dust ingress. The flat head design ensures a neat, professional finish while distributing the clamping load evenly across the mounting surface.

Ideal for Vibration Dampening and Blind Fixing Applications

RFOR rubber nut inserts are ideal for applications requiring vibration isolation, noise reduction, and secure fixing in thin or brittle materials. Installation requires access from only one side of the workpiece, making them an excellent solution for blind fixing applications where access to the rear of the panel is unavailable.
