My guitar has a Kahler tremolo bridge/locking-nut from the 80s that is no longer made. The allen nuts on the locking-nut have long since stripped making it impossible to lock.I couldn't find the same size/thread of allen nuts, so I bought this to replace the entire nut. However, the allen nuts included are the same size and thread as my original Kahler, so I didn't even have to install it.BTW, this did not come with installation screws or any instructions. Not that I needed them.
