[TowerTalk] "Stake all nuts"; what does it mean?

[Speer, Douglas]

I used a lock washer, torqued a first nut then installed a second nut on my equalizer plate bolts.  Is this an acceptable practice?   After two years in service,  I have not seen any evidence of any loosening.

The instruction sheet that came with my Rohn guy equalizer plates states:

"Stake all nuts after assembly"

The kit of parts includes bolts, regular hex nuts, and "PAL nuts".  Assembly order is that the regular nut goes on first, then the PAL nut with the edge lip out.  IE, the flat side of it faces the regular nut.

Questions:

Do I torque the regular nut nice and tight with a wrench, then install the PAL?  Do I tighten the PAL nut finger tight, or gently tighten it just a little with a wrench.  I have no experience with these PAL nuts, but they don't look like they would withstand much torque.

Finally:

What does "stake all nuts" refer to????
I am imagining whacking them with a hammer or something ... but that can't be right?

Note:  the Rohn drawing is dated "1964" :-) Been licensed since 1965 and have never seen PAL nuts before.
