Secure your assemblies with confidence using our Rubber Nuts - the versatile fastening solution designed for vibration-resistant, watertight performance. Also known as Well Nuts or Rawl Nuts, these inserts are made from durable synthetic rubber with a brass threaded insert. These clever fasteners expand as you tighten the bolt, creating a secure hold behind panels or in blind holes, and are a cost-effective solution as once they are removed, they can be reused.

Ideal for soft or thin materials like fibreglass, plastic, and sheet metal, Rubber Nuts are perfect for marine, automotive, electronics, and general DIY applications. Their built-in sealing properties make them a go-to choice when moisture protection or isolation from vibration is critical.

Installation is quick and simple, just insert the Rubber Nut into a pre-drilled hole and tighten your screw. As the insert is drawn in, the rubber compresses and expands behind the panel for a snug, reliable grip.
