Description
rubber nut fasteners give installers a blind-hole threaded insert that also behaves like a compressible sleeve. The Specialinsert metric Rubber-Nut uses a rubber body with a captive metal thread so a mating screw can expand the sleeve behind the panel, creating a retained thread where backside access is limited.
rubber nut applications
Use this insert for panels, covers, light housings, access doors, signs, electronics enclosures, and thin-wall assemblies that need a removable screw without welding or through-bolting. The flange seats on the front face while the body expands as the screw is tightened. That compression can help isolate vibration and seal around the hole when the joint design and material stack are appropriate. Browse related rivet nuts and Deform-Nut fasteners.
installation notes
Drill or punch the correct clearance hole, insert the body from one side, then tighten the mating screw until the sleeve expands behind the panel. Do not overtighten thin materials, since the compressed sleeve needs room to grip without tearing or distorting the substrate. Confirm thread size, grip range, flange diameter, and screw length before ordering replacements for an existing assembly.
