Allen wrenches are sold in sets and not expensive. Moens are not metric so any set of small SAE allen wrenches will contain the right size for your Moen.

It is a 1/8 inch allen wrench. Do not overtighten the bolts. You can crack the wood. Wishing you a happy baby!

if you are having trouble removing the set screw make sure you are using the correct size allen wrench and confirm that it is a allen screw and not a trox screw. After doing this try tighten the screw slightly before loosening it. This should break it loose.

I hope this will help please go to this web site for a downloadable parts link. If it is leaking from the spout replace the seats and springs to correct the problem. Turn water off and remove handle with a 1/8" allen wrench and remove retaining collar to access the ball assembly to remove the seats and springs.

The parts page on this link will give you a break down and hope this will help.

try 1/8

If it is just replacing the handle you will only need a smaller screwdriver set (pretty common) and an allen wrench. I don't know exactly what size you need but you can get a set of these wrenches pretty cheap at any tool or hardware store. Basically the tool is a hexagonal rod that is bent in the shape of an "L". You'll need the smaller set for this job sold usually in sets that have a range of sizes from .05" to 3/8" diameter. I would guess your hex nut is 1/8" or less.

On the bottom of the handle between the sink bed and the handle you'll be able to feel a small hole. When you stick the allen wrench in there it should fit snuggly if the allen wrench wiggles a lot go to the next size up. Since the screw is facing up you will pull the other end of the wrench toward you. This will loosen the screw. It will not take a lot of effort so if you have to force it make sure the allen wrench is actually seated. Kind of a pain but you'll have to reposition the wrench as you get it loosened to fully extract the screw.

Once the screw is out the handle will drop down and the cap just pulls off. Assembly is reverse but make sure that your screw is going into the threads without resistance before tightening. This will prevent cross threading.

Turn off water

Remove the handle with an allen wrench, usually 1/8".

Unscrew the dome with a pair of channel lock pliers with a rag to prevent scratching.

Wiggle out the old cartridge with the channel lock pliers.

Clean all innards with WD-40.

Reverse procedure

Hi,
Make sure the exact allen key is in the screw. take a small adjustable wrench, close it onto the allen key, and loose with wrench turning the allen key.
