It is a revolutionary, international patent pending, press-in insert with mechanical anchoring to create threaded seats on panels, even thin, made of marble, granite or other stones, and moreover on composites, carbon, Corian, HPL, glass and others compact materials.
Keep-Nut is manufactured in stainless steel and is made of a threaded bush, with a set of toothed spring washers, and a plastic ring holding the parts together.
It comes in different lengths, with or without flange, to fit to several different panel thicknesses. It’s easy to be installed since you need just to drill the material with the correct hole diameter and press-in the insert.
Additionally it can be customized with different versions and sizes (inches and metrical), in order to fit the customer needs.
The Keep-Nut insert is specifically developed for kitchen and bathroom countertops, ventilated facades, wall-coverings, décor and interiors, furniture, funerary art, and many more.
A comparison amongst different ways of installing undermount sinks has proven the competitive advantage of the Keep-Nut.
