Nuts for Anchor Rod
Nuts for Anchor Rod
(OP)
We have some high strength stainless steel anchor rods and the contractor is having difficulty sourcing high strength nuts to go with them.
Is it reasonable to use a double nut of a lower strength material, using the thread shear capacity of both nuts? It may be that the steel from one nut or the other starts to yield before it engages the strength of the second nut.
Any thoughts?

The problem is that it is possible to have nuts machined from a higher strength material, but I was hoping to use two nuts of a more common material.

I'd have the contractor keep searching, unless those nuts are guaranteed to be tight against each other, which I guess you can spec, and then peen the threads to keep them in place or a tack weld (but this may not be a good idea), I'd be wary all of the threads would engage at the same time.
Is there a lower strength coupler or similar device that gives you more threads so you get the same capacity?
