Schwarz is right. This stuff writes itself. Remember Chris's nutsaver article?
Go read it.

The article is about a method of tightening the depth stop nut on the tool pictured below. The stop will frequently slip if it's finger tight, and using pliers on soft nuts is unspeakable--even if they're big, and made of brass like the example below.

Here's my recent spin on it on keeping your nuts tight:
I just cut a screwdriver groove with slitting saw:

For me, it is a WAY more sensible/simple/elegant solution to reach for the chip breaker driver (that's already on the bench) than it is to go get a special-purpose strap wrench.

Now I can snug it up with the same screwdriver I've got with me already!

If I'd not had access to a milling machine and slitting saw, I'd have done the same with a simple auger-bit file like this one:

(Possibly one of my "all time favorite tools of all time")
The screw under that big brass knob is a SMALL #10-32, so any self-respecting neanderthal could easily twist the head off with a big driver like the one shown. Obviously a screwdriver can't work on the fence nuts, but I've not had any trouble with my fence slipping. Supposedly, a bit of texture on the rods with fine sandpaper is highly effective for that. AND it's simpler and faster than trying to get a strap.
I hope this helps!
