Electrician Family shows the process of putting in 2 Security Gate Arms for a Facility, Thoughts?

I want to have a little bit of the nut. I don't like to damage the threads, so I always have the nut. Go another half inch. Nothing. Just go another half inch. Good. Let me see what that is. >> Um 11/16. Yeah, put these washers on now. All right. Throw it in. It's got nylon nuts. Okay. So, if this gets hit, these nuts just strip out and this comes right out. Also, there's a shear pin right here. Yeah. So that if it starts to force its way up or down, Yeah. it'll break the shear pin instead of damaging the unit. It's nice. Really nice. Assembled in Mexico, it says.
