Rubber Nuts are blind fastening solutions designed to provide secure fixing, vibration damping and sealing in thin or fragile materials. When tightened, the rubber body expands behind the panel to form a firm grip while isolating vibration and preventing water, dust and corrosion ingress. Ideal for applications requiring electrical insulation or protection of finished surfaces, rubber nuts are commonly used in automotive, electrical enclosures, HVAC, marine and general industrial assemblies where one‑side access is required.
