[jexn8BBWP]

Hello 

I cannot find at standard type in the "treads" menu for the DIN standard, ea 45, 61, 71 and so on?

and I know of the Treads.xls fil but I cannot find all the data needed for creating a file for creating this type of treading.

Hi,

Have a look at this post https://www.symetri.co.uk/insights/blog/customising-thread-defaults/

This looks similar to a Buttress thread, if that's true this page has plenty information on threads

Are these plastic bottle threads?

If so, perhaps the DIN 6063-1 standard is the one you need.

This page could be helpful too.  https://www.fidel-fillaud.com/en/advice/plastic-bottles-its-all-in-the-neck

Or this one:https://www.astm.org/d2911_d2911m-16.html

Do you need a cosmetic thread, or do you need to model the actual geometry?

Now that I look at it, your answer makes more sense.

The way they are named matches op's post and DIN 6063-1 are buttress threads for plastic containers.
