Lot of ado about nothing. You can't say "This thread is useful, this one is not." You are not the Head Mother Fucker in Charge.
Corps used to come up with proprietary threads, after they standardized.
I have, I think, a 128 TPI tap. Feels like a poorly finished turning. But it is indeed a tap. Was there a need for it? Obviously there was, or it would have never been made. It HAS been used mre than once, so, once upon a time, it was useful, and possibly even a standard size. For what, I don't know.
That there IS such is proof that there WAS a need . It is not a one off.
