Identifying the Allen Wrench Size

What is an Allen wrench?

An Allen wrench, also known as a hex key or a hex wrench, is a type of wrench that is used to tighten or loosen bolts and screws with hexagonal heads. Allen wrenches are available in a variety of sizes, and the size of the wrench that you need will depend on the size of the bolt or screw that you are working with.

How to identify the Allen wrench size for a Moen faucet?

To identify the Allen wrench size for a Moen faucet, you will need to find the hexagonal-headed bolt that is located on the back of the faucet handle. This bolt is typically located near the base of the handle. Once you have found the bolt, you can use a ruler to measure the width of the head. The size of the Allen wrench that you need will correspond to the width of the bolt head.

For example, if the bolt head is 3mm wide, you will need an Allen wrench that is 3mm in size.

Using the Allen Wrench to Repair a Moen Faucet

To remove the faucet handle, you will need to first turn off the water supply to the faucet. Once the water supply is turned off, you can use a flat-head screwdriver to pry off the decorative cap that covers the screw that holds the handle in place. Once the cap is removed, you can use an Allen wrench to loosen the screw and remove the handle.

How to adjust the water flow

The water flow of a Moen faucet can be adjusted by turning the adjustment screw located on the back of the faucet handle. To increase the water flow, turn the screw clockwise. To decrease the water flow, turn the screw counterclockwise.

How to tighten the faucet handle

To tighten the faucet handle, you will need to first apply a small amount of plumber’s grease to the threads of the handle. This will help to prevent the handle from sticking. Once the grease is applied, you can use an Allen wrench to tighten the screw that holds the handle in place.

By following these steps, you can easily identify the Allen wrench size for a Moen faucet and use it to repair the faucet. If you are not comfortable working with tools, you may want to consider hiring a professional plumber to help you with the repair.
