BTW, I'm thinking of bars over the kitchen window on the deck. That will
quickly become the weak point. Only real way to attach is from the
outside, and anyone with a few minutes and a ratchet could remove it.
I've seen tamper proof screws in McMaster, but most are pretty short.
Does anyone know of a good source of tamper proof fasteners? Would like
to find some lag screws with some sort of tamper proof head.
If I can't find any, I'll probably just CNC the heads of a bunch to a
shallow oval shape, case harden them, and make a special socket. Pretty
busy right now however and I'd just as soon buy something if it's
available.

Fast & Dirty:

Get a lag & cut off the head
Get a tamper proof lug nut set from NAPA
Weld nuts to lags
