nut sizes on threaded rods: log home
I’m catching up on some things a careless builder (don’t ask!) left undone on a log home. Saddle notch corners are reinforced with long thru-bolts. Some of these are missing the nuts to tighten them up as logs shrink. I took one of the original nuts to the hardware store, where it fit perfectly on a 5/8″ coarse thread bolt. Bought some 5/8″ nuts that fit the same bolt, but they do not want to thread onto the thru-bolts that the original nut threads onto perfectly. What am I missing here?

Could you have gotten some fine thread nuts mixed in with the coarse thread ones?

He bruised the threads in the building process and the nuts wouldn't thread on. You need a die to clean the threads

Is the bolt galvanized and the nut not? or vise-versa?
Also, there are 3 thread classes, 1,2, and 3, with 3 being the tightest tolerance. A low end sized class 1 bolt will let any nut thread onto it, a high sized class 1 only a class 1 nut, etc.
