I have an Omega C760 enlarger I bought a few years ago at a school sale. It's missing the thumb screws that secure the color head onto the frame. I've tried every screw I have around the house and none seem to fit. I would like to replace the screws so I can adjust the gap between the head and the negative carrier. Anyone have know the size/pitch of the screws?
Thanks
 
Using different brackets the C760 lamphouse can fit several Omega enlargers. Most have no other model number on them. The only thumb screw I can see in the manual looks like this:


That is for a B66 or B22 enlarger. Which is one I don't have, at least I don't think so. If that's the one let us know, maybe someone will have one.
Most likely many of the other screws are the same thread. The instructions also mention a black tab bushing.

I have the manuals - the thumb screws are #11 -

I can't find any screw that will thread into the holes. Maybe they're metric. I have a lot of screws in my junk box, but none will fit.

Picture helped. They are 10-32 nylon thumb screws. The threaded portion is 3/4" long. The ones I have look a little different then the manual, the head is smaller in diameter and thicker but they came from the same place on the bracket.

Thanks. The 10-32 screws worked.
