T-Nuts can be used to secure our threaded stem casters to wooden items. Here we show the typical use of the T-Nut for both a Horizontal and a Vertical Application.

In the Horizontal Application, you would drill a hole equal to the diameter of the barrel of the T-Nut and completely thru your wood. Hammer the T-Nut into the hole and thread your caster in from the bottom. This is the strongest mounting.

The Vertical Application is for attaching casters to the bottom of legs and into the end grain of the wood. This is not an exceptionally strong way to mount! Drill your hole equal to the diameter of the barrel of the T-Nut and to the depth of the length of the stem of the caster plus about 1/4″. Apply 2 part epoxy to the T-Nut for additional strength. Hammer the T-Nut into the hole and thread your caster in from the bottom. You must use epoxy as we have had problems with some woods where the nuts ( and the casters ) fall off.
