What Size Allen Head To Adjust String Height?

I'm out of town and left my wrenches at home.:confused:

Which model have you got?

Some (mostly overseas, Mexican) have a 1.5 mm tool size; many American ones (all of mine) call for a .050 inch tool. Sears had both last time I checked.

Before you buy some, detension the string and rotate the grub screw by hand, from the underside of the saddle; it usually works.
