My memory of working on the problem is from probably at least two or three years ago, but I'm fairly sure that the Beseler screws, just based on visual appearance, don't seem to be machine-bolt threaded; they look a lot like sheet metal screws, but apparently aren't quite the same--unless they're some non-standard size. No, I didn't force anything, so when I locate the proper fit, the holes in the enlarger should still be fine.

According to the parts list they should be #4BT 1/4 for 45MXII. 3/8 for 45MXT . Self tapping screws. Some pictures here http://www.shamrockifc.com/screws.html
