Note to all: These will also keep your white tuners from getting dirty and nasty looking. I highly recommend these chrome plated sockets. You may have to fashion a knob or handle. Clean your dirty white, tuners with comet cleanser and give away your aluminum ones.
PS, buy a 5 mm one also. It is a few thousandths larger than 3/16". It's good for tuners that were put on un-threaded and expanded just a little. RP
