To be safe, box them up and send them to me. ;-) Seriously, screw terminals are more likely to come loose than the fast on tabs, because any counter-clockwise pressure on the ring terminal (tension on the wire) will try to loosen the screw. And proper ring terminals take the same space as fast on terminals. If you're thinking of just hooking the wire under the screw head, don't go there. Five years from now, when you're making changes to the panel wiring, you'll be cussing yourself as you lie on your back under the panel with your legs in the air, trying to find the screw you dropped into the bowels of the a/c. Now if you want the Honeywells for the looks, or you believe you need space-certified internal quality, then go for it.

The tabs on the Carling switches I have go straight out the back. When you add the female connector it adds almost an Inch. I just need the room and the NT Honeywell switch is just a couple ob bucks more than the Carling ones. There are also two versions of the Honeywell , One has silver contacts the NT does not. That could really be overkill.

No wins have ever even gotten loose nor do the machine screws when correctly installed and torqued. Space limitations and wire loom routing would never work with Fast-ons. YMMV.

My original post was intended to be a bit light hearted, but it's not a falsehood. Yes, if everything is done properly, screw terminals will be secure. But try half installing a blade terminal on its blade, and half tightening a screw on a ring terminal. Then see which is more prone to loosening when the wires are wiggled. I know none of us who are perfect pilots and perfect a/c assemblers would ever make such a mistake, but 'stuff happens'. The real point is that quality blade connectors are plenty good enough for aviation use.
