Question about bolts from engine to engine stand

[ponytug]

As you know from your own experience, when you have torqued your nut on the bolt and lock washer, the lock washer is effectively flat. The Navy's (and other's) observation is that the standard slightly spiral lock washer has about the same anti-loosening abilities of a flat washer, which the lock washer resembles in use.

Two nuts jammed on each other are pretty good in a high vibration environment, and if it works for you, go for it! The Nord-Lock is better, though.

All the best,

Huh? To me that's a non-sequitur. I don't follow.
It's still a spring, no matter if it's flat (while torqued). Thus it is not equivalent to a flat washer.

...though 40+ years of a anecdotal evidence could be wrong...

Learn something new everyday.
Never heard of a Nord-Lock before. Remember seeing one in the washer supply though.
Wonder what I took it off of?
Now I'm in a panic!
What if it's the bolt that keeps my old hot rod from falling apart?
I shant be sleeping well tonight.

It sounds like a wrestling move..... nord-lock.

Didn't we discuss those before? Sounds familiar. We have a lot of machinery here that use a flat washer, a lock washer, and two nuts. All small stuff, around 1/8".

It was discussed recently. I used the Nord-locks on the chipper conversion that I did as the chipper seemed to have the potential to be a high vibration environment...

All the best,
