Mike- This is great, I'm learning about sizes I didn't know existed. I got the bigger bolt from Numrich, specific to the model 94. They called it a 1/4-24, which I'd never heard of. But my thread gauge said Yes, 24 to the inch, and it fit. Did I guess right that the smaller, Tenite-specific, 24-thread screw was a 12? I was able to measure the thread count, but I had no gauge or screw that matched the diameter.
I also never knew you could buy blank screws until I came across them at Midway while looking for 6-40s for Grandpa's Baker 1897. Now I can see why having some of the less common sizes of taps/dies would be a good idea.
