Lock washers don't work?

I would think more surface = less PSI so the fastener wouldn't be as tight.

What you want is good clamping force .. a function of the correct torque of the fastener. Spreading the same force over a broader area doesnt affect the tightness of the bolt at all, and gives more uniform clamping. The smaller area does equate to more concentrated force [higher psi] .. same force over smaller area. This is very seldom a good thing for the clamped pieces.

No...safety wire is safety wire. In a high stress application (aerospace) in which loose fasteners can result in a catastrophy, I wouldn't suggest using anything but safety wire.

... i was just kidding about using MIG (a Russian cold war fighter jet) wire on a DC9 from the same era...
Sorry, dont know much about aviation, i just like word jokes

Now that I get it, that's FUNNY! There has to be a joke in there somewhere about using 6010 rod for MIG welding.

I suppose this post is a bit late, but whatever. I read a pretty good article a couple weeks ago about fasteners. It was written by the guy who runs Pirate 4x4, which is the hardcore off roading equivalent to Tractor ByNet. I thought the article was well worth the time it took to read, so I figured I'd post a link to it in case anyone was interested.

I guess I'm frugal. I tend to take a simple grade 2 nut and turn it onto a bolt a couple of threads then hit the open side with a hammer slightly deforming the nut creating my own lock nuts. I have had great luck this way.

The threaded studs in the gearbox of my muck spreader are locked on the backside by hitting the thread with a center punch, axially to the thread. Any deformation will work.
