Keep Nut: Information on alternative mounting of holders in hard materials.

23.01.2023.
Our innovative fastening option in natural stone, concrete, HPL/CPL, glass and other materials.

As an official partner of Specialinsert S.r.l., HA-CO Group is pleased to present you this innovative and completely new system. Get an overview of the different benefits and application possibilities in the following article.

The Keep-Nut is made of stainless steel and consists of a threaded bush, a set of serrated spring washers (crowns) and a plastic ring that holds the parts together - in various lengths, with or without a flange, for different slab thicknesses.

The main use is for creating threads in marble, granite or other natural stones, composites, carbon, Corian, HPL, glass and other solid surfaces. The simple and fast press-fit assembly without adhesive and the mechanical anchoring in the receiving material make these inserts a revolutionary and reliable fastening system.

Depending on the type and mounting location, up to 490 kg of extraction forces per insert can be ensured. We can also manufacture custom Keep Nut for special projects thanks to our specialized supplier.

Uses for Keep Nut's are:

  • ventilated facades, stone claddings
  • Interior decorative elements
  • Furniture construction
  • Kitchen and sanitary covers
  • For stone work e.g. gravestones

What could be easier than drilling a hole, checking the depth by means of OK / NOK gauge and inserting the keep groove by means of a standard tool. That's it! No gluing, no expensive drilling with undercut, low material costs and therefore cheaper installation costs. Simple, fast and efficient.

These are the advantages of Keep Nut:

  • Drill cylindrical hole with standard tools
  • Quick installation by pressure - saves time
  • Easy handling and storage of panels
  • No impact of forces in the panel
  • Load distribution is optimal due to the crowns
  • No unscrewing possible due to the thread stop

Our sales experts will be happy to present the products to you in more detail and advise you on your project.
