Keep-Nut® - 4 Crown - M5

Our self-anchoring stainless steel Keep-Nut® 4 Crown insert is the highest-strength option in the Keep-Nut® range, engineered for maximum anchoring in dense materials such as granite, marble, stone, composites, and solid surfaces such as Corian®. Installation is straightforward: drill to the correct hole diameter and press in the insert — no adhesives, no resins, just secure mechanical fixing.

The four-crown configuration provides superior pull-out load capacity and torque resistance, ensuring long-term stability in demanding applications. To enhance safety and performance, the thread stops before the end of the insert, preventing accidental extraction caused by over-length bolts.

Manufactured from stainless steel, with a plastic ring that holds the insert components together, the unheaded Keep-Nut® 4 Crown insert delivers exceptional corrosion resistance, precision, and durability — ideal for architectural panels, furniture assemblies, façades, and exterior applications.

If your application requires less anchoring force or a thinner substrate, explore our 1 Crown or 2 Crown Keep-Nut® inserts for alternative pull-out strengths. Shop them here.
