[Elecraft] KPA100 Middle Side Screw Alteration

[W3FPR - Don Wilhelm]

Roy,

McMaster-Carr http://www.mcmaster.com/ has self locking Threaded Inserts -
their PN 90248A016 is 4-40 threaded ID and 6-32 threaded OD - 10 per
package.

OTOH, Elecraft offers #5-40 taptite screws for those who have stripped the
threads - free on request.

73,
Don W3FPR
