Bottom Bracket Installation Question

I am building up a new frame and decided to as much stuff as possible even if it's new a foreign to me. The BB installation seemed like a breeze based on videos and write ups so I bought the right Park tool and headed to work. Both sides went in fairly smoothly and most of the way by hand. It looks centered. My question is this...the cap piece on the non-drivers side sticks out a tiny bit. It looks to be in straight and it went in very easily but at the end when it was at it's tightest point there is a few MM sticking out still. Is that the normal way it's supposed to be? Here are photos.

Yes. Some BB's do stick out a bit. As long as you've met torque specs, and the spindle spins freely by hand with no side play, albeit with some viscous friction, then you're good.

What's most important is not a few exposed threads but the proper torque and chainline. If things are torqued right and you chose the correct bottom bracket it will work fine.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

It should be the right size for the crank I am getting by all documentation that I have seen. I assume you are meaning size-wise (this one is 110mm). All of the instructions I have seen online have just mentioned tightening it as tight as you can with a socket wrench. No mention of torque specifics.
