T-38, T-45 & T-51 Threads

[jvw86]

Can anyone shere with me the specifications for these threads? I'm trying to detail a Pin & Box for each of these threads and having no luck finding the standard.
I need the usual Major, Minor diameters, pitch, thread shape with flats & fillets etc.
Any help would be greatly appreciated.
Thank you.

I don't recognize these threads, but try this BBS. Someone there may be able to help.

Also, go into the rooms dealing with machining. This room is for soil testing.

Thanks, I'll try there.
I posted here because this thread is used on drilling / core sampling equipment.

T38, T45 and S51 are rock drill steels ( to be used with top hammers on drilling rigs ). You will certainly find the info from an Atlas Copco dealer but I doubt you can do what you want. These drills are made with special steels and receive treatments which allow them to work under very hard conditions. I doubt that you can economically manufacture any durable accessory by yourself
