I've never had one stick in that particular situation, but I usually
replace oddball screws/bolts with something more common as/when I find
them (I hate "tamper proof" crap).
A hacksaw blade in one of the grooves would probably square it off and
deepen it enough to just get a flat-bladed screwdriver in - then ditch it
and replace it with something sane...
That's what I would typically do also, but my guess is that the OP's
screws are in a "hole" and not accessible with a hacksaw blade.
I just did a quick interweb search and it seems that all of the bits
available are "long reach" bits like the ones at the HF site, implying
recessed screws in most, if not all, cases.
I add my support to the claims of no authorization
required to obtain Tri-Wing bits and screws...
They are NO LONGER considered security screws,
they are however an improvement to vandal resistance
over standard slotted, Phillips, Torx, Allen and Robertson
fasteners... Even the screws and bits with the "security"
shafts in them are no longer considered security...
If you are looking for something truly secure and of
limited distribution then try this company --
Bryce Fastener of Gilbert, Arizona...
They offer true security fastener products...
Yup... Good but expensive... We had issues with people
trying to disassemble doors and locks on the loading docks
and the panels inside an elevator cab to try and access
unauthorized area for a mall I used to work at...
A few thousand of these bolts in several sizes and three
different bit sizes to install and remove them and no one
could take any of the trim plates off the mortise locksets
to unlock them using the stopworks under the trim piece...
Although you can use these screws with a screw gun I
would not recommend it, as you can FUBAR the bit a lot
easier and often times you are using the fasteners on
delicate things you wouldn't want to use a screw gun on
in the first place like door lock trim coverplate pieces,
coverplate screws on electrical boxes and the like...
If you don't want to buy into something that is totally
unique to you, the Penta-Plus fasteners are definitely
a step up from anything that claims to be a "security"

The cost of repairing and replacing the damaged
equipment is usually much greater than the cost of
$2-ish per fastener to secure it using the security
The point behind using security fasteners is to
NOT allow people to put something back together
after they have taken it apart to covertly access
Not to mention, to intimidate them into not even trying, and going
elsewhere. Anti-vandal fasteners will at best slow down a professional
thief. But professional thiefs are rare. Much more common is an idiot
kid or druggie, and if all the fasteners don't match any of the three
tools they brought with them, they may decide that if they can't get in
quietly, it isn't worth the trouble or risk.
