Thread Standards
(OP)
Hi,
I'm going crazy trying to find the dimensions for thread forms called T-38, T-45 & T-51. They are specified on rock drill equipment. I'm trying to design some addition fittings but can't find this info to supply a CNC programmer.
Can anyone out there help?!!

KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?
RE: Thread Standards
The threads are on sectional drill rod. See the attached catalog, bench and drifter drilling, for applications.
It has been a long time since I was associated with rock drilling manufacturers. If I come with another source, I will post it.

RE: Thread Standards
Also they may be in FED-STD-H28.
There are dimensions for all 3 threads you mention.

RE: Thread Standards
This is not a Tr (trapezoidal) thread. It is similar to a rope thread and has a large pitch, the T-45 pitch is .735" and the T-51 is .790".

See page 609 of this book review:

I worked for a manufacturer and contacted other manufacturers for industry reference material. Especially if I was designing something that would connect to their product. These threads are not proprietary.
