How far can you over drill the .375 deep hole and how are you measuring I.D.thread depth? A bottoming tap will get you full threads about 2-3 turns from the bottom. With the O.D. thread can your .375 length go to a thread relief or is the .375 the last witness mark where the single point thread tool pulls out?
You can go to .400 on the depth if need be. When these are assembled, we will be using a 6-32 X 1/4" round head screw.
We have the need for 50 to 100 of the 2020M-5 stud as noted in the drawing. Dimensions are shown. Material can be cold roll steel, drill rod or tool steel - essentially what you have available. The max dimension is .185 / .187 , so 3/16 rod is adequate.View attachment 268423
FWIW, making a thread length dimension to +/-.005 is kind of silly. My preference (and it is practical as well IMO) would be xx rev full thread, or .375 min FULL thread, maybe with a note of .5 max, if needed for the function of the part.
It will make the part easier to make and quote IMO...
Well - if he's only using a 1/4" long screw like he said - you guys can figger the rest eh?
Even if he doesn't understand the issues.

I'd like to think it obvious that I was talking about the inside hole?

No kidding. Your comment seemed to imply people didn't need to be asking questions that they were. My question about the O.D. thread was not answered and neither was Mike's.
My point was that the opp doesn't seem to know how to spec his print well, but once he disclosed that what he really needs is to be sure not to bottom out his 1/4" screw, then we all understand what he "needs", but maybe not what he spec'd.
Come on, we all know that someone that draws a flat bottomed hole on a napkin with threads spec'd to the bottom - prolly aint draftsman, but with the added info - we should be able to assertain what he needs, and deliver that - and at a price that is much better than if we actually took his napkin to heart.
But then - there would always be the one time that the guy DID actually need that, and your parts would be rejected and you would be shamed on a public forum lynching too.
I mean - come - on, if you went by the print 100% you would be chasing a LH thread on the OD end....

Thanks, now what about the other end?
