T-Nut — Pronged & Hammer-In
T-nuts have a flange with sharp prongs (or barbs) that anchor into wood when hammered in. Once installed, they provide a strong threaded insert in wood, plywood, or MDF. Standard hardware for climbing wall hold mounting, furniture leg connections, and turn-knob assemblies.

Frequently Asked Questions
How do I install a pronged T-nut correctly?
Drill a clearance hole of the specified size (typically slightly larger than the bolt diameter). Position the T-nut on the back side of the workpiece with prongs against the wood, then hammer the flange flush. The prongs bite into the wood and prevent the T-nut from rotating when the bolt is tightened.
