Method to calculate material around internal threads
Method to calculate material around internal threads
(OP)
Hi,
I believe this problem was raised here:

I can't seem to post to it since it is closed. The question I have is if you decide to use the short answer method
"The short answer is to use the same number as the width across flats on a hexagonal nut of same/similar strength/size to your part."
and the yield of the material you are threading is less than the yield of a nut would you scale up the width based on the yield ratio? Example:
nut width = x
Yield nut =Sn
Yield material to tap = St
Required width =x * (Sn/St)

The proof strength on the equivalent nut is about 90ksi, I intend to use 44ksi material. Is there anyway to calculate a minimum width for internal threads other than using VDI 2230?
