Rubber Nuts for Materials up to 50.00mm Thick

The RFOR Rubber Nut Insert is a versatile fastening solution designed to provide a secure, vibration-resistant threaded fixing in materials up to 50.00mm thick. Combining a durable brass threaded insert with a neoprene or EPDM rubber body, these rubber nuts offer excellent sealing, vibration damping, and corrosion resistance across a wide range of applications.

Designed for installation into a pre-drilled hole, the rubber nut expands as the mating screw is tightened, creating a strong fixing behind the panel. This blind fixing action provides a secure mounting point while helping to absorb shock, reduce noise, and protect against moisture and environmental contaminants.

Ideal for Vibration Isolation and Sealing Applications

RFOR rubber nuts are ideal for applications where access is limited to one side of the installation or where vibration and movement can cause conventional fixings to loosen over time. The flexible rubber body provides excellent vibration isolation while creating a weather-resistant seal around the fixing point.

Suitable for indoor and outdoor environments, these inserts are widely used in automotive, marine, electrical, HVAC, and general engineering applications.
