Bolt-On neck pockets should be 5/8" deep.
So that's the most crucial and epic pic I would need to see, the rest of the pics have no context or meaning w/o that.
The neck removed and a ruler sitting upright next to the heel to see final height.
If you finished it yourself, did you go back and sand all, or nearly all, of the finish out of the pocket?
That is a standard issue protocol for anyone building their own guitars, to level-sand the neck pocket after finishing/before assembly.
Nearly all the way back to wood, with just a slight amount of (dead-flat) finish left on it.
You'd be surprised how fast a glob or blob of finish will jack your action up.
And...Warmoth, I'm sure, is well aware of exactly what I just mentioned for people not used to rolling their own.
Take the neck off, measure the pocket, sand out all your finish except a paper-thin and flat layer.
THEN, resultant string action pics will have some context and meaning.
There is no reason to have to over-tighten neck screws.
That is some sort of band-aid instead of identifying and fixing the real problem.
On a Mahogany neck, you'll strip out the screw holes faster than you can blink your eyes.
Maple is tougher, yes, but you can still strip them out, depending on the particular piece of wood.
All necks are not the same as far as screw-tightening abuse is concerned.
Some strip out very easily, some not so much, just depends.
But the moral here is that it is never necessary to do that to 'fix' something.
