: I am looking for information regarding the number of threads that should project above a nut on an anchor bolt. I have always heard the bolt should project atleast the thickness of the nut above the nut. today it was suggested to use 1.5 the dia. of the bolt above the nut. I know there is a standard, but I have not been able to find it.

: Thank You

I think that if you get at least a couple of threads beyond the nut then you have full functionality and strength of the bolt. I've never heard of the 1.5 rule for extra threads but, it does not hurt to be sure you have full thread engagement.
