Check your local hardware store. Usually they have odds and ends of specialty hardware in small cardboard pull out drawers. You should be able to find some "TEE Nuts".

Tee nuts are made in steel and brass and come in a number of varieties.

Some just have a flat plate while others have a plate or circular head with sharp corners extending upwards.

To install the TEE nut you first drill a hole through your wood large enough for the tubular TEE section to fit in. The Tubular section is then inserted in the hole and in the case of the nuts with sharp protrusions you ligthly tap them in with a hammer to lock them in place.

You can then extend a common SAE thread machine screw or bolt from the front side and screw it into the female threads in the hollow tubular section of the TEE nut.

Tee Nuts are commonly used to attach table legs.

I use the tee nuts and the old Wood floor type watercloset bolts to attach table legs. The wood floor type closet bolts have a 1/4-20 SAE thread on one end and a Wood Screw Thread on the opposite end.
