Keep-Nut® - 2 Crown - M4

Keep-Nut® 2 Crown is a self-anchoring stainless steel insert providing balanced strength and easy installation in stone, marble, granite, composites, high-pressure laminates, and solid surfaces such as Corian®. Installation is quick and clean — drill the correct hole diameter and press in the insert, no adhesive or resin required.

The dual-crown design delivers enhanced pull-out resistance compared to the single-crown version, making it ideal for medium-density materials and moderate load applications. The internal thread stops short of the insert base, avoiding extraction if an excessively long bolt is used.

Manufactured from stainless steel, with a plastic ring that holds the insert components together, our unheaded Keep-Nut® inserts provide exceptional corrosion resistance, durability, and flush fitting — perfect for architectural, interior, and furniture installations.

If your project demands higher or lower pull-out performance, view our 1 Crown or 4 Crown Keep-Nut® inserts to find the optimal solution for your application and load requirements. Shop them here.
