Nut for fixing end member to shoulder rest bar. Nut supplied may vary slightly from illustration. Nut for KUN Super is brass. See photo.
The nut that drives me nuts to be without.
Pros: Just what was needed. It's really great to be able to buy this nut. It is a crucial item for happy playing.
Other: It's great to have this locking nut available but i don't know if you sell the other nut, the one with a whole in it like a small polo mint. I haven't yet lost that one but may do one day.
