I'm about to fit a new bridge to my Chibson and have bought a Gotoh Nashville-type, with the correct metric studs. My problem is that the studs are very slightly smaller in diameter than those they are replacing. The one on the treble side can be pushed in under finger pressure, and pulled out easily in the same way. On the bass side the position is even worse; it just drops in and, if you turn the guitar upside down, drops out again! Admittedly all will be held in position by string tension, but I wasn't sure it was a good thing for the studs to be this loose so called my local luthier and explained the problem.
He agreed it shouldn't be this loose. I asked if it would be permissible to just wrap a turn or two of masking tape round each stud before tapping them in and he said some might do it that way, but a better solution would be to get some of the gel-type superglue and smear it round the inside of each hole, until the hole was small enough for the stud to be tapped in. (He said you could just glue both studs in, but they then would be difficult to remove; you'd have to heat them with a soldering iron to get them out again.)
So I'm going out now to buy some gel-type superglue and will let you know how I get on!
