Press in Self-Anchoring Threaded Inserts Formed of Stainless Steel and Plastic

For those who aren’t aware, these are high strength press-in, self-anchoring, threaded inserts that are rated up to 562 lbs per fastener. They can be used for undermount sinks, wall panels, facades, furniture, and more.

Installation is simple. It involves drilling a shallow, cylindrical hole into the surface to be mounted on, and driving the Keep-Nut into it with a rubber mallet. That’s it. This anchoring system is especially suited for automated shops where all the holes can be plotted on CNC equipment. Once the holes are drilled, the fastener is installed in seconds which saves a lot of time and labor.

Advantages include:

• Compatibility with thin materials (including 2 cm- down to ⅜” depending on variety used)
• Shallow hole depth (<¼”) means less drilling in granite, less wear on bits, and less time on equipment
• Quick and easy installation
• Incredible strength (up to 562 lbs per fastener)
• Special drills can be used to prevent cracks from the high heat created when drilling into natural stone. Ask about the CNC and Gas Drill Bit (11.8 and 11.4mm)

The Keep-Nut series are threaded self-anchoring fixing systems for marble, stone, ceramic, artificial stones, sandtones, klinker, laminated HPL.
