Performance Tool M980 Emergency Lug Nut Removal Set, Black

I used this to remove a locking lug nut ( the things you put on in place of a regular lug nut that requires a special key wrench to remove , so it is harder for someone to steal your wheels of your car ) . My key wrench had broken , but they also get lost of course. My locking lug nuts were completely round and hardened , so very hard to get a grip on and then apply enough torque to break lose . This tool has reverse threads so it bites when you are unscrewing a log nut 9 or bolt or nut . AS you can see 2 sizes come in the set but they have to be pretty exactly the size needed for your particular application. The range of sizes they fit are listed on the packaging . I did learn one thing in using them which is that you must UNSCREW THEM from the nut you have just revved rather than just knocking them off with a hammer because the fine threads can be damaged making the tool useless . Best way I think to unscrew them is to get an appropriately size bolt that the nut fits ( same as the studs of your wheels) , then screw the old nut onto it all the way , put the head of the bolt in a strong vise and screw the tool with nut stuck inside off by turning clockwise as if you were tightening it on . I also hear some tire shops have tools to remove locking lug nuts with out the key wrench Also when you buy a replacement set of locking lug nuts make sure the key looks unbreakable and buy 2 sets so you have a spare key. some locking lug nuts and their matching keys are only meant to be used with hand tools , NOT AIR WRENCHES !!! Ok now you know what I spent lots of time and money to figure out . You're welcome .

Still in the package, need it for my car. A good thing to have.
