Anytime you want a nut that won't come loose, get on with a nylon insert.
These are called "shake proof" or "Nylock"  and can be had at any large
hardware store for about a nickel a piece. You can use them alone or as a
jam nut over the top of the regular one, assuming there is enough thread
left over.Geo>K0FF

>Hello,

>I purchased a new KT34-A about a year and a half ago.  I now have a
>tower and I am assembling the KT34-A for the first time out of the box.
>I have reached the point where I am mounting the element sections to the
>center lexan insulator.  The manual states "that the nuts are only
>tightened until the lockwasher starts to close."  The manual states that
>over tightening could result in insulator failure due to differences in
>temperature coefficients between the steel screws and the lexan.  I am
>tempted to tighten the nuts down further with my fingers and just a
>socket because I am afraid that if I barely tighten as stated in the
>manual that they will come loose over time.  Does anyone have any
>experience with this subject?  Is it ok to just tighten the nut down
>until the lockwasher just starts to close?  Will it hold up over time
>without loosening?
