Work Instruction for Thread Length Measuring??

[jpolley8714]

I am having a problem with a customer involving the thread length on a double ended stud, in the effort to clarify both parties views, I am trying to create a Work Instruction showing how to measure thread length. I would like to include "full thread" and "total thread" for a double ended stud, but would like to go a step further by adding Lg and Ls(or body length) on standard cap screws. I can only find a old IFI standard from 1982 that shows some of the information I need. My question is, is there another standard out there I can use as reference?
Any suggestions would help.
Thank you in advance............

The current edition of the IFI handbook is the 7th ed. Published in 2003, so you might want to start there.

It contains all of the ANSI standards that define thread dimensions.
