Was looking for some protection for my BBS discs. Of course, no lock is completely secure, I'm just betting on the assumption that if you can make it harder for a would-be thief, they'll either get past it or take long enough to pick it that it increases the likelihood that someone she sees and they get scared before they're done. I like their design because you can't just hammer the special socket on the outside to take it off because the outside wall rotates freely inside the "key socket" which is too oddly shaped and thin to knock the socket in her easily. I would definitely recommend them if you are concerned about wheel safety. Also note that you can contact Gorilla and have them send you matching sets of these nuts - this way you can replace every single nut on every wheel. This further increases the time it takes to remove the wheel and ultimately the chance of saving the rim! As another reviewer mentioned, the images match the actual product. I received the Gorilla Store model 63631 as stated in the description. Please check their website first and make sure it is the type of nut you require.
