You keep going on about this one little screw - what about the connections, the installation checks etc...?
Most of these rules are in place to protect people on the ground as well as the lump of meat behind the control wheel, past experience tends to shape the rules - unfortunately many people have over inflated opinions of their own abilities and tend to find themselves in all sorts of trouble.
Not saying this is the case with your good self just the reason the rules are there
