Description
Overview:
The Mason Mate Rubber Anchor Nut, size M5 x 15, is a compact, expanding fastener for fixing into thin panels and hollow sections where rear access is limited. The rubber body compresses and expands when an M5 screw is tightened, gripping the internal walls of a cavity for a firm, vibration-damped hold. It is suitable for use across construction and garden machinery, from engine shrouds and guards to control panels and covers. The M5 thread accepts standard M5 machine screws, and the 15 mm body length suits many common panel and bracket thicknesses. Made from durable black rubber for dependable performance, this anchor nut is sold individually so you can buy exactly the quantity you need for maintenance, repairs, and fit-out tasks.
Key Features:
- M5 internal thread with 15 mm body length for versatile panel and cavity fixing
- Expands securely inside pre-drilled holes without rear access
- Rubber body helps absorb vibration and reduces loosening on machinery

Ideal for dashboards, fairings, cowlings, housings, and electrical enclosures where only front-side installation is possible. Useful in vehicle bodies, trailers, tool cabinets, and fabricated assemblies requiring tidy, removable fixings.
