What size Allen wrench is used for Moen faucets?

Moen is a brand of American faucets inventor Alfred M. Moen. However, most of us don’t know their faucets’ exact Allen wrench sizes.

Faucets

A faucet is a fixture for drawing or regulating the flow of liquid, especially from a pipe. Faucets can be found in sinks, bathrooms, kitchen, and shower fixtures. There are different types of faucets.

  1. Ball faucets – Ball faucets have a balled-shaped cap on the top of them. It is a single-handle faucet. Move the handle from side to side to control the temperature.
  2. Disc Faucets – It has a single-lever control and a wide cylindrical body. To control the temperature of the water, use the two ceramic discs at the bottom of the chamber inside. This is the latest faucet.
  3. Cartridge Faucet – Cartridge faucets have a consistent and smooth feel across the twisting axis. A cartridge faucet has lever-style handles turn as opposed to round, valve-style handles. The difference between cartridge faucets and compression faucets is the way they work.
  4. Compression Faucet – Compression faucets have double handles for hot and cold water lines. When you turn it on, there is less pressure and more pressurize as they close. They are frequently found with round knobs. This is the oldest type of faucet when compared with the rest.

Allen wrench

Allen wrench is also known as hex key.

Allen wrenches are handy tools designed to work with screws that have Allen’s head. These screw heads usually have a hexagonal shape and a thin slot in the center, which is where the wrench will be able to fit.

The thin slot in the center of the Allen screw head lets it work with both Phillips and flathead screwdrivers, which means you only need one tool to maneuver around these different types of screws.

These screws are used for various purposes, such as new home construction and repairing furniture.

Because there are so many useful applications for Allen head screws, it follows that there are many Allen wrench designs, sizes, and styles to make working with Allen head screws easier.

Allen wrench sizes

Allen wrenches are measured in both millimeters or inches. Allen wrenches vary from 2mm to 25mm.

The standard sizes of Allen wrench come in inches. They are 1/16, 5/64, 9/64, 7/32, 3/8, 1/8, 3/32, 7/64, 5/32, 3/16, 1/4 and 7/32 inch.

However, standard European size Allen wrenches come in millimeters. They are 1.5, 2, 2.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8, 9 and 10 mm.

The most common sizes are inches 1/8, 3/32, 7/64, 5/32, 3/16, 1/4, and 7/32. In millimeters, they are 2.5, 3, 4, 5, 6, 8, and 10.

Which Allen Wrench size do I need?

Here, I will be answering some of the questions people have raised about their Allen wrench size for Moen faucets.

  • I need to replace the cartridge in my Moen Extensa faucet. I can’t get past step 1 of undoing the set screw that holds the handle on. 3/32″ is small, and 1/8″ is big. 

7/64″ will work fine. Moen will probably send it to you when you buy the faucet from them.

Make sure that the Allen wrench is brand new and the right size, or else you won’t be able to get the Allen key to enter the screw. Well, I ended up buying a new one so that if I ever deal with this again, I have the wrench, too.

  • My bath has a Moen single-lever shower that controls no hot water. What can be the issue? I tried using Aleen keys, but 2.5 mm too small and 3 mm too big. Which size should I use?

7/64 size will work.

There may be a clogged cartridge or a spun balancing spool. On a Moen cartridge, there are two flat spots on the brass rod. If you look closely, there is a little extra notch on one of those flat spots. This extra notch must point toward the handle when you assemble the faucet.

Moen seems to have their own size. Set-screw stuck. Some are star-type patterns, and you can get them at the local hardware store. There is a set of hex wrenches that come similar to a set of jewelers screwdrivers, and that will have the size you need. Also, Bondhrus sets come in odd sizes. They have small wrench size sets and medium-sized sets.

  • I have a pressure-balanced Moen shower fixture, and the size is 7/32 hex. That, of course, doesn’t fit what you tried to use. If this fixture was purchased in Canada, would it be a metric set screw?

Call the Moen number. They will tell you what size it is, and they might even send it to you in the mail. Maybe it is a 7/64 Allen wrench you will need.

  • I’m trying to remove the faucet handle on a bathroom sink so that I may replace the cartridge. Is the “bat” part of the faucet separate or cast into the stem?

A rubber (non-slip) jar lid opening pad (aka “screwy Lewey”) ought to work using a firm grip & twisting counterclockwise. Don’t use pliers, just in case it is NOT a screw-in handle (riveted).

The handles themselves can be removed safely with a nylon strap wrench, but check to see if there is a removable cap on the top of the cold and hot controls to see if there is a screw under that. You unscrew the whole base, and it will lift off and expose the cartage.
