Reviewed in the United States on April 2, 2013
Size: 1/2-inchVerified Purchase
Get a cheapo 3/4" to 13/16" crowbar adapter if you need to keep your proprietary crowbar. If not, just buy a new crowbar because- and this is no big deal, the usual 1/2" thread to 3/4" grab is not present here for the sake of a bigger acorn shape to the nut. I love these so much, it really does not present a major obstacle.
Gorilla actually sells a great adapter too. They're not jacking you either. It's just the way things are in life. I will browse and buy again and again from these guys. Their selection and prices are terrific.

These lug nuts are constructed very well. I use an impact wrench to remove and install them and the coating is strong enough that it isn't chipping or scratching. The bulge ensures they don't get pushed into the socket. They are all uniform in color and weight. They made a huge difference in the appearance of the wheels and I've gotten several comments on them already.

I bought these because the local parts stores didnt have anything I liked or cared to buy e.g., "Made in China".... They are of good quality and what I like is that when I go to take them off 1. they arent easily scratched and 2. they have a collar that keeps my socket from scratching the rim when I remove them and when I go to torque them down.

Product was exactly what I wanted. Forgive the new/unwashed mount look but the tires and rims are 1 hour old so just got them home and haven't washed yet.

1.0 out of 5 stars Edit: Rust!!!!!! Too early, but good so far...but re-check torque on nuts!!!!
Reviewed in Canada on May 24, 2017
Size: 12-mm X 1.50Verified Purchase
Too early to tell on durability, resistance to rust etc. Out of package, look as expected. I wish I could get a gloss black to match the gloss black centre cap, but minor issue. I would caution when using new nuts...check the torque of the nuts again after 30 miles or so. I have heard this warning over and over again, but never paid much attention because I have never had an issue with nuts coming loose. However, this time, we used these nuts on a used set of RX-8 wheels. Well sure enough, Mazda 3 was going in for oil change and we were hearing weird whomp whomp sound, subtle but noticeable, from front driver side. Asked dealer to also look into this and while at the service desk, mechanic turns around and asks "have you changed your wheels lately?....likely loose nuts". No way I say...we used a torque wrench set to 85 ft lbs as always. Well sure enough, driver front wheel has two loose nuts, one is so loose it is not even in contact with wheel. Re torque, all good...noise gone. Likely cause is that although nuts are supposed to have same seat angle, because used wheels with different nuts, the could be off slightly thus having less contact and thus, being more susceptible to coming loose. Moral of story, always recheck your wheel nuts after install, especially if using NEW nuts.

Edit: Frustrating. 2 summers ( no winters) and the Gorilla nuts and lock nuts are rusting. Not happy. Contacted Gorilla and they chose not to stand behind their product. Even more frustrating. Will never buy Gorilla again.
