Wheel Locks???

My last car was an 87 Sundance. Not too many people were attracted to those nice steel rims hidden under $15/4 plastic hubcaps...

I noticed today that there are four bolts in the spare tire styrofoam. I have seen lug nuts, but I've never seen lug bolts. Do these cars really have bolts rather than the good old fashioned lug nuts? Anything special to know in order to put these "locking lugs" on the car? Must I torque them to a particular setting?

Has anyone had to replace the "key" that is supposedly easily bent up? I'm curious how much damage the stealers get for those.

Thanks for the information.

I always rotate my tires and this one time one of these security nuts striped. There was no way I could take it off. It cost me $100.00 to have the nut drilled out. I changed all the nuts to regular nuts.Yes VW does not use a nuts but a bolts.
I've heard of a few other people who striped their "NUTS".
