Q: What is a t-nut?
A t-nut is a flanged fastener with barbed prongs that anchor permanently into a pre-drilled hole in wood, giving you a strong metal thread to bolt into from the other side.

A t-nut is a flanged fastener with barbed prongs that anchor permanently into a pre-drilled hole in wood, giving you a strong metal thread to bolt into from the other side.
Drill a 29/64" pilot hole, then hammer the t-nut's three prongs flush into the wood so the flange seats against the surface and the threaded barrel sits ready to accept 3/8-16 hardware.
These three-prong t-nuts (3/8-16 thread) accept standard 3/8-16 bolts and machine screws, with a 1" flange diameter that spreads the load across the wood surface.
Not necessarily; each of the three barbed prongs bites into the wood grain as the flange seats flush, resisting rotation and pull-out under normal clamping loads.
