Heres a review I found on the net about them.....
I first installed the screws on our sacrificial test case. Knowing that we were most likely going to destroy the screw points of said test case, we chose a hideous pink case that had also been responsible for frying a motherboard, due to poorly constructed motherboard standoffs. So I guess you could say it was a personal vendetta. Anyway, we installed one gold and one black screw on the case. We tightened each screw down with the included screwdriver as tight as we could get them. Then we set out to remove the Security Screws!by any means necessary. First we tried the good old vice grips. Despite our best clamping efforts, the little screws held strong. The rotating outer rings of the screws really did keep us from getting a good grip!the rings just spin around the head of the screw, preventing would-be thieves from actually turning the neck of the screw. The rotating outer rings of the screws are slightly tapered, which also helps to keep unwanted tools from getting their metallic teeth around the outer ring.
Next we tried blunt-nosed pliers, no luck. Needle-nosed pliers proved equally as useless as did wire snips and tweezers. Frustrated, we went at them again with the vice grips. This time around we succeeded only in destroying the poor outer ring, thus making it impossible to remove the screw even with the included screwdriver. Time for the big guns. The large reciprocating SKIL saw made short work of the insolent little screws and melted lots of pink plastic in the process.
We decided to test them again. This time I installed two new screws with the included custom keys. I was able to get more torque with the keys as the screwdriver head had a tendency to slip off the 3-pronged gold screw heads. Once again we let loose with the destruction. This time, however, we tried a pair of smaller needle nose pliers and attempted to grab a hold of the actual screw head itself as opposed to the rotating outer ring. With a large amount of elbow grease and at just the right angle, we were able to remove the screws. This was the only way we were able to extract the Security Screws (without the help of a power tool). The smaller needle nose pliers were just tiny enough to fit around the pronged screw heads and eventually twist them free, but it wasn't an easy task.
