It's pretty common to use beads of some type on the end of your strings when stringing up a through-bridge uke. I went looking for some the other day, and came across these on Amazon. They're 6 mm in diameter, but more important, they have a hole through the middle that allows you to mount them with just a simple stopper knot, AND the whole is just big enough for even a Low G string (I checked).
