[Elecraft] K3 bottom cover screw spinning in place

[Don Wilhelm]

Mark,

Re-reading that screw location - it may mate with a standoff - so you 
may be able to remove the top cover and tighten the screw that fastens 
the standoff to the main board.  Easy if you have the basic K3, but a 
bit more complex if you have the SubRX installed.

Mark,

It certainly sounds like either the screw itself or the threads on the
K3 are stripped.
Do not take the dremel tool to it.  Instead, use a thin tool (like the
point of a knife blade) to insert under the screwhead and pry it upwards
while turning it with a screwdriver.  There is no captive hardware on
the other side.

Examine the screw carefully - if there is a place where the threads on
the screw are stripped, you should throw that screw away and request a
replacement from Elecraft (parts at elecraft.com), but if the threaded part
of the K3 enclosure is stripped, that is a more serious problem -
consult K3support at elecraft.com for advice and assistance.
