I need a locking nut for my Gehmann 530 rear iris on my FWB 2602. Does anyone know a convenient source for these nuts? I want to screw it in and lock it so as to see the index mark in the 12 o'clock position.
TIA

Locking nut
I would go to a hardware speciality store first, with the iris, and match it up to a metric, thin, probably hex head nut. If you have no success that route then I would email or better yet phone Champions Choice. They may have to order one unless they would take one off a stock item and order one for themselves. If you've bought there before they may accomodate you. They seem like good people.

metric nut
The problem with this nut is that it is an unusual thread (9.5mmx 1mm). I am planning to call CC later and see what they have.

Additonally, you may want to obtain a small, thin washer (just larger than the screw assembly) to serve as a spacer. I used two on my Centra and it lined up the centering dot. Then a slight tighten on the lock nut.
