Mating Threads
Mating Threads
(OP)
When designing threaded parts that mate together, (for example a threaded bottle neck and a cap), are there generally gaps or spacing anywhere designed in to for tolerances? Or are the mating threads line to line? It seems like there should be some sort of gap but im not sure.
Thanks!
Thanks!

Can you recommend any websites or literature showing mating thread profiles?
Thanks

I.e., .010" or so.
There are 'standards', but I've had better luck just detailing a part to mate with whatever part I could buy.

So, rather than talk to a mech engineer about threads - as if this was a conventional thread problem, I'd recommend talking in depth to the design/fabricator company of the bottling machine that you will use.

If you are designing a custom cap to fit a commercial bottle, or conversely, I stand by my advice. It's worth at least what you paid for it.

If at all possible start with one of these.
