Tapered Rib Faucet Aerator Wrench
This is a one-size-fits-most wrench for faucet aerators that are stuck. It has a tapered socket lined with 24 ribs. The opening narrows from 31 mm at the mouth to 16 mm at the floor, so any round aerator shell in that range, from tom-thumb to full-size, seats where it jams and the ribs grip it without stripping the shell the way pliers do. A 140 mm gusseted handle gives the leverage, a 10 mm drain hole in the floor lets water run out, and a 6 mm hang hole is at the end of the handle.
Toilet Tank And Fill-Valve Nut V-Wrench
A 175 mm long, 8 mm thick double-ended V-wrench with serrated 90° jaws. The large end grips plastic fill-valve and flush-valve locknuts and wing nuts from about 40 to 75 mm across. The small end takes tank-bolt wing nuts and supply-line coupling nuts from about 16 to 38 mm. Being plastic, it won't crack porcelain or chew up plastic threads, and you can reach into the tight space under the tank.
