ALPIDEX 500 special t-nuts M10 DIN EN 12572-2-2017 zinc-plated professional fixation with chipboard screws

T-nuts are used to fasten climbing holds on a wooden wall. Hereby T-nuts act as the counterpart of hexagon socket screws.

The absolute advantage of the special T-nut “Professional” is that it is not hammered down, but fixed with two chipboard screws from the backside of the panel. This way a T-nut will never loosen again on your climbing wall!

In order to fulfil the high and strict safety requirements for this important connecting element, our drive-in nut is tested in accordance with DIN EN 12572-2-2017.


  • Material : zinc-plated steel
  • Tested according to DIN EN 12572-2-2017
  • Metric internal thread M10
  • Thick-walled design (Plate thickness approx. 2 mm)
  • Height of T-nut (incl. of plate): approx. 12,0 mm
  • Plate : 40 x 25 mm
  • Required pre-drill diameter: ca. 12 mm
  • Special T-nuts are fixed with 2 chipboard screws (diameter: approx. 4 mm)
  • Fastening of climbing holds with standard M10 screws


The PROFESSIONAL special drive-in nut offers you a high-quality alternative to the standard drive-in nut. It also has advantages over other special drive-in nuts that are installed with 4 chipboard screws. The reason for this is not only the halving of the labour required to fasten the PROFESSIONAL special drive-in nut, but also its load-bearing capacity tested in accordance with DIN EN 12572-2-2017. This is because the two holes for the chipboard screws have a much larger diameter than the four holes in a conventional special drive-in nut. This means that thicker screws can be used when installing the PROFESSIONAL, giving your climbing holds the optimum hold.


First of all mark all positions where you would like to place the special T-nuts with the help of a grid. A hole grid of 10 cm (95 special T-nuts required per sqm) or 15 cm (45 special T-nuts required per sqm) is recommendable for boulder walls. Every other row should be staggered. Another possibility is to use the exactly as many special T-nuts as climbing holds. The disadvantage of this layout is that there are only very few options to fasten the climbing holds on the wall. Furthermore you would have to dismantle all panels if you plan to extend your wall. Drill 12 mm holes where you marked the spots for your special T-nuts. Place the special T-nuts “PROFESSIONAL” from the backside of the panel into those holes and fix them with two chipboard screws.
