What size Allen wrench is needed to remove a Moen shower handle?

The size of the Allen wrench needed to remove a Moen shower handle can vary depending on the specific model and design of the shower handle. Moen shower handles often have a set screw or hex screw that holds the handle in place. To determine the appropriate Allen wrench size, you can follow these general steps:
1. Identify the type of set screw: Examine the shower handle to locate the set screw. It is usually located underneath the handle or behind a decorative cap. Determine whether the set screw has a hexagonal socket or an alternative type, such as a square or star-shaped socket.
2. Measure the set screw socket: Use a set of calipers or a ruler to measure the width across the opposite flats of the set screw socket. This measurement will help you determine the size of the Allen wrench needed. If the set screw has a square or star-shaped socket, you will need a different tool, such as a square or star wrench.
3. Obtain the appropriate Allen wrench: Based on the measurement of the set screw socket, select the corresponding size of the Allen wrench. Common sizes for Allen wrenches used in plumbing applications include 1/8", 3/16", 7/32", and 1/4". However, it's possible that a different size may be required for your specific Moen shower handle.
It's important to note that Moen shower handles can vary in design and require different tools for removal. In some cases, specialized Moen handle removal tools may be necessary, especially for older or more complex models. These tools are often available from plumbing supply stores or can be obtained directly from Moen.

If you are uncertain about the correct Allen wrench size or encounter difficulties during the removal process, it is recommended to consult the user manual provided by Moen for your specific shower handle model. The manual may include instructions on handle removal and provide information on the appropriate tools to use. Additionally, Moen's customer support can provide guidance or recommend the correct tool for your particular shower handle.
