1/8 wrench for that one.
The correct hex/allen wrench to remove a Moen faucet handle (for the Renzo model faucet) is 7/64".
we have had this faucet for a long time and I have done several repairs on it, because it has a lifetime warranty Moen sends us the parts and it is simple to repair. To remove the handle, carefully remove a small plug on the front of the handle, some have the Moen name on them and the one that we currently have is the same color as the faucet. You can remove them easily with a small knife or screwdriver, just make sure not to scratch the finish on the faucet. Under that plug you will find an screw that uses an Allen wrench (3/32), loosen it and the handle will come right off by lifting up on it. To get to the rest of the faucet just lift the dome and the cartridge is ready to remove with a wrench. Don't remove the cartridge without turning off your water source!
7/32
An Allen wrench is a hex head wrench - a screwdriver with a handle and hexagonal head at right angles to each other.
The cap does NOT come off. It is all part of the handle. To take the whole handle off, there is a set screw at the back that can be undone with an allen key. The older discontinued models, the cap can be pried off with a small screwdriver.
You need 7/64".
As with any answer...it depends, but try this: If the faucet is the single handle type, use an Allen wrench to remove the small set screw from the handle, (if the handle set screw has too much mineral build up, wrap the handle to include the set screw with a paper towel. Secure it with a rubber band; and then soak with vinegar and leave it for several hours) "Break" the seal of the set screw using the Allen wrench, and remove the handle.The remaining parts, under the handle, will probably have the same problem. Use the same process. At this point turn off the valves leading to the fixture (you may have to turn off the water at the meter) Continue dismantling, use the correct and appropriately sized tools. This should help but if your faucets have been neglected for a long time, probably plan to replace the faucets.Hope this helps...
9mm Allen wrench
You need a 3/8 Allen Wrench
Most likely a 15mm wrench. Unlikely to be Allen in that vehicle.
7mm Allen
