What Our Gearhead(R) Experts Are Saying:"I used these T-Nuts to reset holds on our home wall and the zinc plated finish held up great through a full season of sweaty hands and hard sends. The 4 prong design bit into the wood fast and never worked loose."Every good climbing wall starts with the details nobody sees. The T-Nuts disappear behind the plywood, holding each bolt on hold exactly where we set it, letting us focus on the route instead of the hardware. We drop them in, tighten down our favorite jugs and crimps, and get straight to climbing.
