Keep-Nut® - 1 Crown - M5

Keep-Nut® 1 Crown is a self-anchoring stainless steel insert engineered for secure, permanent fixings in stone, marble, granite, composites, high-pressure laminates, and solid surfaces such as Corian®. Compact and simple to install, users only need to drill the material to the correct hole diameter and press in the insert — no adhesives or resins required.

The single-crown configuration provides reliable anchoring for thin materials or low-load applications, delivering stability without compromising surface aesthetics. The crown expands mechanically within the hole, creating strong resistance to pull-out forces. For added reliability, the internal thread stops before the end of the insert, preventing extraction from using an excessively long bolt.

Manufactured from stainless steel, with a plastic ring that holds the insert components together, the unheaded Keep-Nut® 1 Crown insert offers excellent corrosion resistance and durability for both indoor and outdoor use.

If your application requires higher pull-out strength, explore our 2 Crown or 4 Crown Keep-Nut® inserts for increased load performance. Shop them here.
