Had to remove a sink the other day, and the shut off valves were the one for handicapped bathrooms, so I needed a special key to shut it off
Picked one up from the plumber, but it turned out to be the wrong size, so I had to get creative
(Not that creative, just a spin on the helicoil setup)
So, we got a 1/4 inch bit holder then a torx bit, and a 1/4 wrench on that
Worked like a charm
