Wes,
I believe Elecraft has already implemented a fix for that in later K3s
(starting about a year ago) - at least there was talk about doing it and
supplying one 2D connector that was different then the others (with
threads removed from thee hole).
Removing the threads from the center hole of the 2D connector eliminates
the dependency for first tightening the screw (really tight) into the 2D
connector and then tightening the standoff (without loosening the screw).
So if you want to fix yours, drill out the center hole of the 2D
connector so the 1/2 inch screw can pass through it (1/8 inch drill
bit). The screw is then tightened when the standoff is added to the end
of the screw.
Be certain to hold the 2D connector in a vise or otherwise secure it
while drilling so it does not spin and cause injury.

Has anyone come up with a permanent fix for the erratic output power problem? I'm not
talking about the 100W PA issue, but the issue "solved" (temporarily) by
loosening and re-tightening the screws in the metal standoff on the output board near the
coax connector.
According to Murphy's Law, mine failed during the DX contest and the chase for
TX5K QSOs. The screw technique worked for awhile but then I had to resort to
tapping on the top of the case near the connector.
Maybe Elecraft can offer an optional hammer to be used for this purpose?
