When putting up security bars, do consider making them open able from
the inside, ok? Id hate to find out one of our posters became a Extra

Thanks for the thought!
When we own our own home I'll go to that effort. Here, the kitchen is
too small to get "trapped" in, and the front door is just a couple feet
to the right. Living quarters are the whole upstairs, and we have an
emergency chain ladder that can be let down from any other window.

As for "security" fasteners, while looking to see if there might be any
bargains on ebay for alarm systems, I ran across a very complete set of
drivers for practically every "tamper resistant" fastener on the market,
selling for under $12. So much for that one..
Think I'm going to custom mill the heads of lag bolts in the three-lobe
profile centerless grinders hate. I think I can come up with a profile
sufficiently close to constant diameter that after case hardening,
nobody is going to get much of a bite on them with vise grips, yet still
be able to get a decent grip with a matching driver.

The last set of security bars I saw installed, had one side hinged,
and the opposite side had a pair of stainless steel rods that came
through the wall, via a couple weathertight grommits, and were secured
on the inside of the room, with a pair of small cotterpin/hitchpins,
backing up a large washer. The cotter pin secured rod ends were under
a small plastic cover, that had a small piece of stainless wire rope
secured to the cotter pins and were pressed on the ends of the rods,
with a wide flange covering the pins and cable for cosmetic reasons,
and then painted to match the walls. One simply pulled on the plastic
covers, they came off the ends of the rods, and one simply continued
to pull and the cotters came out of the rods, and then one simply
pushed the bars out of the way and escaped the flames. They appeared
quite simple to make, very low profile and not the least unsightly,
and if one had drapes, the drapes covered the two covers completly.
