Farm implement threads

Farm implement threads

(OP)
I hope someone can help me. My team is investigating a field failure where the field crew bought a piece of all-thread and nuts that they claim is threaded with what they called a farm implement thread and then used it for something completely different than it's intended purpose. I have not put eyeballs on this part myself yet, but I've been told it looks like a 1"-7 stub acme thread (I don't know how much stock to put in that however). I need to know what kind of thread this is and what materials/strength standards if any might apply to such a piece of all-thread. Does anybody know?

RE: Farm implement threads

I think we need some specific details in order to help

RE: Farm implement threads

look under Acme Threaded Rod in McMasters:
http://www.mcmaster.com/
They list carbon steel, Stainless, & A-193-B7 (= good stuff, but not weldable)

Maybe you got the "ungraded" steel?

RE: Farm implement threads

Let me be perfectly clear, I do not know it to be a stub acme thread. It may very well be something completely different. I am told they bought it from their local John Deere dealer. I have never heard of a "farm implement thread" standard, nor has anyone else I work with.

I think also, that is some missunderstanding. If you want to look US agr. machinery standards, you can find them at ASABE:
