Secure modules [RE-wrenches]

[Nicholas Ponzio]

I have also found these security fasteners at McMaster-Carr
http://www.mcmaster.com/. Tamper Resistant machine screws with Pin-in-Torx
Head (stainless) & breakaway nuts in aluminum.

William,
Great advice and good technique, but I think Kurt was looking more for an
anti goddam thief device.
I use a BIG pop rivet tool and 1/4" steel or SS rivets. You can drill out
the steel jobs, but the stainless ones take a grinder. Unlikely a thief,
being basically lazy, would have it together or go through the trouble.
Probably end up to be more expensive than your Fastenal solution, but fast
and pretty bomb proof.
Best to all on the Holiday.
