To pull an old two- or three-handle tub and shower stem, you need a deep, thin-walled socket set. The Superior Tool 03755 is the long set for valves buried behind tile, and the Danco 60505 is the standard thin-shell set; both cover the same five double-ended sizes from 21/32 to 1-7/16 inch.

Shower valve socket sets compared
| Set | What you get | Choose it when |
|---|---|---|
| Superior Tool 03755 | 5 sockets + turner bar; 25% longer than standard per maker | Valves are recessed deep behind tile |
| Danco 60505 | 5 thin-shell sockets + handle and carrying pin | You want the common retail set for most bonnets |

A shower valve socket is a thin-walled, deep tube with a hex on each end. It slides over the stem of an old two- or three-handle tub and shower valve to reach the bonnet nut sitting inside the tile, where a normal socket or wrench cannot fit.
The five sizes that cover most valves
Danco and Superior Tool list the same five double-ended sizes. Danco’s page (danco.com) lists 21/32 & 27/32, 29/32 & 31/32, 1-1/32 & 1-3/32, 1-5/32 & 1-9/32, and 1-11/32 & 1-7/16 inch, and Superior Tool’s product sheet (sites.salsify.com) lists the same five pairs.
That spread covers the bonnet nuts on most older compression tub and shower valves. If a nut falls between sizes or has been rounded, stop and reassess rather than forcing a loose socket; a rounded bonnet makes the job much harder.
To find the size, measure across the flats of the bonnet nut with a caliper, or try the sockets from larger to smaller until one slides on with no rocking. Note which end fit and write the size on the valve’s access panel or in your job notes so the next repair goes faster.
Each socket has two sizes, one on each end, so five sockets cover ten sizes. Keep the bar in the kit; it passes through the cross hole in the socket to give you leverage without a ratchet.
Superior Tool 03755: the long set
Choose the Superior Tool 03755 when valve stems sit deep behind thick tile. Superior Tool says (sites.salsify.com) the set is 25% longer than standard tools for recessed valve stems, includes five sizes and a turner bar, and uses heavy-wall zinc-plated construction meant not to slip or round out valve stem edges.

Danco 60505: thin shell for tiled walls
Choose the Danco 60505 as the standard set for most jobs. Danco says (danco.com) it removes and installs tub and shower valves, fittings and nuts, fits most shower valve bonnets, and has a thin shell that lets it reach deep into tiled walls. It lists five sockets with a handle and carrying pin.

Eastman 45041: a basic set sold by Amazon
Choose the Eastman 45041 if you want a basic five-piece plumber’s socket set with a bar handle. The listing describes it as a 5-piece plumbers socket set with bar handle in silver; it does not list the sizes, so compare against the five standard pairs above before you rely on it for a specific valve.

Removing a tub and shower valve stem
Shut off the water to the house or the bath, then open the faucet to drain the pressure. Pull the handle and escutcheon; you may need a handle puller if the handle is stuck. Our faucet handle guide covers handles and pullers.
Choose the socket that fits the bonnet nut snugly, push it all the way on, slide the bar through the cross hole and turn counterclockwise. Steady pressure works better than jerking, which can round the nut or crack old tile.
Take the old stem to the store or identify it by brand; stems are specific to the valve. Our faucet seat wrench guide covers the seat behind the stem, which is often worth replacing while you are in there.
Buying a single socket instead of a set
If you already know the bonnet size, a single socket costs less and takes less room in the truck. Danco sells its deep stem sockets individually (danco.com), such as the 86642 in 1-1/32 and 1-3/32 inch, describing a stainless thin shell that fits deep into tiled walls.
Choose the Danco 86642 for that common size. On October 15, 2026, the standard new offer from a third-party seller showed limited stock with model and part 86642.
The Prime-Line Rapid Repair RP77312 is another single socket; its listing gives 29/32 and 31/32 inch. On October 15, 2026, the standard new offer sold by Amazon.com showed limited stock with model and part RP77312.
A set still makes sense if you work on different valves, because the bonnet sizes vary by brand and age.

Putting the stem back in
Clean the threads in the valve body and inspect the seat with a flashlight. Replace the washer and screw on the new or rebuilt stem, and put a light coat of plumber’s grease on the stem threads so it turns smoothly and comes out easier next time; our plumber’s grease guide covers what to use.
Thread the bonnet in by hand first, then snug it with the same socket. Do not crank it; over-tightening can damage the bonnet threads and makes the next repair harder.
Turn the water back on slowly with the handle off and check for drips at the bonnet before you reinstall the escutcheon and handle.
When a socket set is not enough
#ad Buying for a shop? Amazon Business (opens in a new tab) accounts are free to create, with business-only prices and bulk quantity discounts.
If the bonnet will not budge, penetrating oil and time help more than force; our penetrating oil guide covers options. If tile or grout sits tight against the bonnet, chip back only enough to get the socket on.
Single-handle cartridge valves usually do not need these sockets; they use a cartridge clip or nut instead. Our shower cartridge guide covers those.
