1/2-27 thread dimensions

[nick_ritacco]

Hi,

Working on a drawing where there is a shaft threaded in 1/2-27. I'm struggling to locate any dimensional data to help with my drawing. Would anyone be able to point me in the right direction, please? A search on this site did not yield any information. Thank you!

1/2 - 27 most likely is a pipe thread - which would be specified as 1/2 - 27 NPT.

There are pages that may be of help. TO be sure, you may want to communicate with the engineering drawing originator.
