A325 N and A325 X
A325 N and A325 X
(OP)
I understand that A325 N means threads are included in shear plain and A325 X means the threads are not included in shear plane.
My question is when would you want to have the threads in the shear plane? Doesnt that effect the connections strength?
When the threads are in the shear plane there is less material and that means less strength. So why include them in
the shear plane? I would think X would be more suited for a stronger connection.

I typically use the more conservative values for bolt size unless I know for sure it can be X.

If you have a bunch of unique connections with different grip dimensions, or perhaps a unique grip thickness with a tight tolerance on the total bolt length, getting the right bolt in the right place to create an "X" connection may not be possible or practical. If the connection can tolerate an N structurally, that'll save your contractor money and time.
I also follow Manstrom's practice, and only rely on the N value unless I'm sure the contractor is able and willing to provide the extra legwork for X.

I have worked with enough of these guys to know that the last thing I want to worry about is if I have specified N or X bolts on a given project.
