#6-80 Threads

[DesertDawg]

We use a #6-80 screw for fine positioning. I'm unable to locate any specs or standards on the threads, or a tap drill size. Does anyone know of a good reference or source? I'm trying to eliminate all possible backlash in our current design. Thank you.

Here is good website for your information you need.
A good machinist or machining handbook would be a great help to you.
