Determining diameter of machined shaft prior to threading.
Determining diameter of machined shaft prior to threading.
(OP)
I'm designing something simple where i need to create an internal and external 9/16-18 threading.
I know i need to drill the bore to 0.5156" prior to tapping
What diameter do i need to machine the shaft to prior to running the 9/16-18 die down it to create the thread?
Thanks

For a .5625-18 UNF-2A thread, the major diameter limits are .5611/.5524.
Good luck.

If you don't want to get that and are willing to accept free information from the internet try: http://www.boltplanet.com/default.asp
Make the relevant selections (you don't have to put values in for the stress calcs) and 'calculate now' A pop up will appear, at the bottom of this is the diameter info for both male & female.
