It’s difficult to find good T-nuts for climbing panels , and we have conducted extensive testing of various suppliers to find ones that meet climbing wall standards. As a result, we have developed our own T-nut type, which is the standard on our walls and is secured with two wood screws. We offer this T-nut in quantities of 1000 pieces, including machine screws for fastening it. The T-nut is extremely strong, with thick material and requires a 13 mm hole. In addition to this T-nut, we also offer a high-quality classic T-nut.
