5. Setup and Installation
This part is intended for replacement of existing Moen faucet handle plug buttons and set screws. Basic tools, such as a small screwdriver (often an Allen wrench, depending on the faucet model), may be required.
Installation Steps:
- Identify the Faucet Handle: Locate the faucet handle requiring the replacement part.
- Remove Old Plug Button (if present): If an old plug button is still in place, carefully pry it out using a thin, non-marring tool.
- Remove Old Set Screw (if present): Use an appropriate screwdriver (e.g., Allen wrench) to loosen and remove the old set screw from the handle.
- Position the Handle: Place the faucet handle onto the valve stem, ensuring it is correctly aligned.
- Insert New Set Screw: Insert the new Moen 113957 set screw into the designated hole on the faucet handle.
- Tighten the Set Screw: Using the appropriate screwdriver, tighten the set screw until the handle is firmly secured to the valve stem. Do not overtighten, as this can strip the screw or damage the handle.
- Insert New Plug Button: Press the new Moen 113957 plug button into the hole, covering the set screw. Ensure it sits flush with the handle surface.
- Test Operation: Gently operate the handle to confirm it is securely attached and functions correctly.
Note: For specific faucet models, refer to the original faucet's instruction manual for detailed handle removal and installation procedures.

The Moen 113957 Plug Button and Screw Set functions to securely attach your faucet handle to the faucet's valve stem. Once installed, the handle will operate as intended, allowing for control of water flow and temperature (depending on faucet type). The plug button serves to conceal and protect the set screw.
7. Maintenance
To maintain the appearance and function of your Moen 113957 Plug Button and Screw Set:
- Cleaning: Clean the chrome plug button with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Periodical Check: Periodically check the faucet handle for any looseness. If the handle becomes loose, gently tighten the set screw.
