Moen Kitchen Faucet Handle Keeps Coming Loose

This kitchen faucet is the moen motionsense arbor model but i believe this should be a similar fix to many different kitchen faucets.

Moen kitchen faucet handle keeps coming loose.

Moen faucets are designed with serviceability in mind. When kitchen faucet handles are flipped up or pushed down too hard the mounting hole in the handle expands or cracks. If too much force is used on the handle while opening or shutting it stems may chip crack or break. The hex size is 3 32.

The handle and base of a kitchen faucet can work loose over time. This guide will help with a simple adjustment like tightening a loose handle. Moen review with 3 comments. If while servicing the product you notice broken or corroded parts please click identify my product as interior parts vary by model number.

Corrosion also plays a role in stem and handle wear because it accelerates cracking and breaking by eating away at the metal. I purchased a 2nd moen lindley brushed nickle kitchen sink faucet last summer to replace the exact same faucet that i had been having the same problem with the handle keeps coming loose.
