Stainless t-nuts for outdoor use
These M10 t-nuts are made from stainless steel and are therefore well suited for outdoors climbing boards.
Drill with a 12 mm drill and tapped in the t-nuts from the back of the board and then secure it with 3 wood screws. Climbing holds can then be mounted with M10 bolts from the front.
We suggest that you make a pattern with about 25 x 25 cm hole distance. It provides approximately 50 posible holds mounting points per. plywood sheet of 125 x 250 cm.
Screws for mounting not included, but can be purchased at any hardware store.
