Internal thread specifications

(OP)
I need specifications for an internal thread that is not common, it is a 3.875-32 thread.  Does anyone have reference to this thread (i.e. pitch dia, minor dia, etc...) or a source for this?  I can't find this thread anywhere.  Thanks in advance...

RE: Internal thread specifications

(OP)
go to your machinery's handbook and use existing formulae for determining whatever dimensions you need.

RE: Internal thread specifications

Internal Pd. 3.8607-3.8547
major Min. 3.8750
Minor 3.849-3.841
External Pd. 3.8533-3.8487
Major 3.8736-3.8677
