These Gorilla lug nuts with the spline tool installed are around 2/3 - 3/4 of the diameter of the smallest 19mm socket I could f
I bought these for my 02 WRX. I had bought some Team Dynamics wheels and the stock lug nuts were too large. The stock lugs used a 19mm nut, with a thin 3/8" 19mm socket they would barely fit in the wheels. These Gorilla lug nuts with the spline tool installed are around 2/3 - 3/4 of the diameter of the smallest 19mm socket I could find which makes them very easy to install and remove. The spline tool fits beautifully around the nuts and a nice shoulder keeps them from being installed on the nut too far and scratching the paint on the rim. They have very very very little play and are easier to install and remove than standard lug nuts. I was not expecting that. They definitely exceeded my expectations. No idea how the paint will hold up, I do not use an impact gun on wheels I care about so hopefully the paint will last. I almost gave them 4 stars because there was a little rust deep in the threads but no matter what lug nuts you buy they will start to get some rusty threads pretty quick so I did not care, and I was so impressed by every other aspect it cancelled out.One other really great thing, most aftermarket lug nuts with a special tool will not help you out if you lose the tool. Gorilla give you a very nice and professional looking aluminum sticker to paste on the car somewhere like in a door jamb that has instructions for getting a new key, along with the address to mail $10.50 to and the registration number of the tool.

More durable than I initially thought
Bought these as sort of placeholder lugs for mounting a new set of aftermarket wheels/tires, but to my surprise the coating has held and the fit is perfect; they look a lot nicer than what I would have expected at this price range too. The fact that they’re spline lugs also gives a bit more piece of mind when parking near sketchy areas.Very happy with mine.

All lugs look the same. No ugly looking key lug to stand out.
Fits exactly like my old lug nuts. They came in a bag with the adapter piece. I was a little worried that they would be scuffed up, but they are covered in a fine layer of some kind of grease. I bought aftermarket rims for my vehicle and my old lug nuts could only be removed with an impact wrench. Using these lugs allows me to use a regular tire iron because of the adapter that comes with them. They fit 3/4" and 13/16". Very good quality product. If my little cap that covers the lugs and wheel hub falls off or becomes cracked or damaged, I will have no problem with letting these lugs be visible. Can't rate the durability yet, because I just put them on today.

Great Lug Nuts
Recently, I had taken the time to sand, prime, and repaint (Semi-Gloss Black) my Steel Wheels wrapped in snow tires that I use for my Subaru Outback during the winter and thought to myself, if I'm going to make the wheels look good, might as well follow up with new Lugs as well. I had 2 requirements for the lugs that I wanted, needed them to be some sort of Semi-Gloss Black and also serve as wheel locks and this lug kit does just that. Gorilla uses a type of spline system for the lugs so that a regular socket or lug wrench could not remove them and they are brilliant. The kit comes with a lug key (obviously) and also comes with a key code so that if the key is lost or additional keys are required, they can easily be ordered.Anywho... highly recommended lug kit that look great and keep your wheels from growing legs and walking away in the middle of the night.

Happy but sad....
I was tired of changing the locally made open steel lug nuts every 6 months as they would rust. So i bought these lug nuts in Black. I must say they fit perfectly and are very strong too. I should have got them in chrome though as my wheels have more chrome than black in them. Anyways that was my mistake, the nuts are of very good quality and i would surely recoment them to my friends. The only and the biggest problem is that they are not available here (India) i had one of my friends visiting the States get me a set. So my suggestion (request rather) is that they be made available in India too as i am sure it will find a lot of buyers.All in all, a good buy but be sure to choose the right finish based on your wheels.

Lug nuts work great
I ordered black lug nuts and received chrome. Other than receiving the wrong color, the lug nuts work great & fit good.
