wow, paying for a moen wrench, thats a new one. I carry the dual and single nut moen wrench. Jam a 1/2 drive socket in the dual wrench and use a speed wrench on the single. Got both nuts covered.

PASCO make a tool called the "Nutcracker" which removes lock nuts from half inch shanks. Works great.

I had a Moen nut that actually broke the tool it was so stubborn.

Solution? 5/8" deep sparkplug socket on an extension with a 3/8" ratchet. Came out easy-peasy.
