T-nuts are basically a threaded nut with a series of prongs on the flanged side of the nut. These prongs once driven into the rear of the plywood panel help to prevent the t-nut from spinning and allow for attaching the holds with the bolts.
The great advantage of the t-nut once that it has been inserted is that you can place the climbing holds from the front of the wall with out having to go around to the back.
T-nuts are available in two types of material. These are steel and Stainless steel.
Depending on the application select the appropriate type.
To insert the t-nut first drill a 12mm hole in the required location in the plywood panel. Then bang in the t-nut into the rear of the side of the climbing wall surface (18mm plywood panel) with a hammer.
If using screw on t-nuts place the screws around the circumference of the flange of the t-nut. Again the flange side of the t-nut is on the rear side of the climbing wall surface (18mm plywood panel).
TIP: Try to make sure you place the t-nuts square to the panel.
Steel / Zinc coated type
- will rust and corrode if exposed to rain or very humid conditions
- cheapest option
- Good for walls that are not exposed to the elements (indoor use)
Stainless Steel type
- Excellent corrosion resistance
- Suitable for both indoor and outdoor applications
- More expensive than regular steel or zinc plated t-nuts
