Nuts for anchors

[Mohamed Maher]

hi

Is it possible to use with anchors in a baseplate one nut only instead of two nuts?

Thanks

Sure, why not?

Ok, seriously, if you want a real answer, you're going to have to provide more information. What is it anchoring? Is it embedded in concrete? Can the anchor bolt turn after installation? Bottom line is that if you can secure it so the bolt or rod and the nut can't turn with one nut, that's all you need. Otherwise, you need to secure it, with another nut, by welding (not usually allowed for anchor bolts), or some other method.

Ensure that a "heavy hex nut" is used if only one nut is used..... If you select the correct material and tighten the nut properly, you can develop the full tensile strength of the rod. (i.e. the rod will fail in tension before the nut "pulls through"

When you see two nuts used on a threaded rod, the upper nut is typically being used to lock the lower nut in place.

Structural Codes and standards require heavy hex nuts
