Rubber Nut Inserts for Materials up to 24.90mm Thick

The RFOR Rubber Nut Insert is designed to provide a secure, vibration-resistant threaded fixing in materials up to 24.90mm thick. Combining a durable brass threaded insert with a neoprene or EPDM rubber body, these rubber nut inserts deliver excellent sealing performance, vibration damping, and corrosion resistance for a wide range of industrial and commercial applications.

Designed for installation into a pre-drilled hole, the rubber body compresses and expands as the mating screw is tightened, creating a secure blind fixing behind the panel. This provides a reliable threaded anchor point while helping to absorb shock, reduce noise, and seal against dust, water, and environmental contaminants.

Ideal for Vibration Isolation and Sealing Applications

RFOR rubber nut inserts are ideal for applications where vibration resistance, weather sealing, and one-sided installation access are important. The flexible rubber body provides excellent shock absorption while creating a secure fixing that helps protect the surrounding material from damage.

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