Caster Tee Nuts and Sockets

These caster tee nuts and sockets give a stem caster something solid to hold in a wood leg or cart. Parts on this page include 4-prong zinc tee nuts in 1/4, 5/16, and 3/8 in threads. Also listed is a Shepherd 5/16 x 1-1/2 in zinc metal socket for grip-neck stems. Tee nuts press into a drilled wood hole so a threaded stem can screw in tight. Sockets seat a grip-ring stem in wood when you do not want a through-bolt. Match the thread or socket size to your stem before you place your order today. Read the listing for the exact size shown. No pound capacity is printed on these hardware titles. Verify the SKU matches your old hardware before you buy. Sizes below are per part as each listing states. Stem casters: stem casters. Threaded stem wheels: threaded stem caster wheels.

Tee nut or socket?

Tee nut: for threaded stems. The barrel goes in a drilled hole; four prongs bite the wood so the stem has steel threads.
Grip neck socket: for smooth grip neck stems. The socket presses into wood; the stem snaps in.

Installing a tee nut

Drill a hole the size of the tee nut barrel, square to the surface.
Tap the tee nut in from the side the stem will enter until the flange sits flat.
Thread the caster by hand first. The stem must not be longer than the hole is deep.
End grain in a leg is weaker; set the tee nut before the leg is attached when you can.

Caster socket questions

What size tee nut do I need?

The same size as the caster stem thread: 1/4, 5/16, or 3/8 in on this page.

Do you have 7/16 grip ring sockets?

Not in the active assortment on this page today. Plastic 7/16 grip-ring sockets exist as drafts only. Call 844-439-4335 if you need a 7/16 wood or tube insert.

Will a threaded stem fit a Shepherd grip neck socket?

No. Use a tee nut for threaded stems and a grip neck socket only for grip neck stems.
