Hi Leigh:

For what it may be worth, I used a flat washer on BOTH sides of the plastic 
case (up against the case itself). Then, I used a hand-held socket to 
tighten the nut. Using the flat washers allowed me to apply a higher amount 
of force to tighten the nut since they spread the compressive forces out of 
a slightly wider area of plastic.

I also used two flat washers between the nut and the thumbscrew, so I can 
sandwich the wire between the washers and not have the thumbscrew try to 
expel the wire as it's being tightened down.

I also used a slightly longer screw and then used a pair of heavy-duty wire 
cutters to impart a 'bunged-up thread' right at the end of the screw. this 
keeps the thumbscrew from being accidently unscrewed and lost.
