Why all the small screws???

Smallest i like to use on machines is 5-40 if i need to push it, 6-32 is as small as i like to go.

On the machinery's handbook note, its a definite must for any machinist or mechanical designer. I use it tons everyday at work. Has everything from horsepower calculations to roller chain sprocket profile construction to threading.... even heat treating and such. The copy i use is old, from the early 80's, its the 26th edition. I don't know how much they can change about it though, has most everything you'd want to know.
