I'm working in a warehouse where they have a carton opener which blade held
by a 10-32 screw. The practice WAS to "CRANK IT DOWN" to keep the blade in
tight; this has resulted in screws seizing (die cast aluminum/zinc body) as
well as some pretty booger'd up screw-slots.
I think a lock-washer would give the proper hold without having to
over-torque the screw. Thing is - they need to take these apart each day to
replace the blade. Can a simple #10 lock washer be reused?
It would seem OK with occasional replacement when it seems to be getting a
little 'flat' and losing its spring.
