Review on Gorilla Automotive 20733 Acorn Hex Socket Combo Packs - 12mm x 1.50 Thread Size: A Comprehensive Solution for Your Automotive Needs by Steven Chiumento

I installed it a few days ago and when I tried to loosen the lug nuts they all started breaking! I could see that the tension was only concentrated on part of the tension nut. I'm glad the tire shop was able to remove them with a percussion gun. I have two keys that both snapped off trying to take this off. I ripped the first one off with a Gorrila wrench and then a broken shank on another nut. .Eventually we determined that the lug nuts were over tightened, but that's still not the only reason the lug nuts broke when trying to remove them. I think the main reason for the break is because of its poor design. Use regular wheel nuts or those that can be gripped from the outside. You won't regret it if you have to remove them. Update 17th October 2011 I ended up getting a McGard 65554 and am happy with it but be aware the star shaped lock key looks the same but is different. ! I had a wrench for a similar McGard lock nut but it didn't work. McGard 65554 Chrome SplineDrive Wheel Fitting Kit (thread size M12 x 1.25) - for 5 stud wheels [.]
