Nut launchers!
Please, lets call them what they are.
Nut launchers.
But really, I use the technique that Dan H. described. Lots of times, you just can not get to them with all the fancy tools. But you can always make a lasoo of safety wire to sinch them. It takes about 10 minutes to be methodical, disciplined, and do it for every nut launcher.
But if you try to take a short cut, and spend an hour with it, plus the bent/broken fingernails, lost nuts, frustration. So, patience grasshopper, use the wire loop method if you can't get a tool on it.
As to twist ties, the best use for them might just be to lassoo the nut launcher closed while you get the bolt through. I haven't tried it, but if it works it would be faster than a safety wire loop.
