[TowerTalk] Rohn EP instructions: "Stake all nuts"; what does it mean?

[Michael Ward]

A*Palnut*is a locking device for nuts which is made of stamped sheet 
metal, and is a registered trademark. The palnut is screwed on the bolt 
on top of an ordinary nut, and has a series of protruding barbs that 
locks the nut in place when the nut is tightened. The Palnut itself is 
reusable. A Palnut should not be used as a substitute for apositive 
locking device 
<https://en.wikipedia.org/wiki/Positive_locking_device>such as 
acastellated nut <https://en.wikipedia.org/wiki/Castellated_nut>or nuts 
with safety wire.
