These nuts are good but not perfect. The finish has some flaws. Nevertheless, they look pretty and you only really see them from afar. I would say if you just want a decent looking nut, want something reliable and decent quality but don't want to spend a lot then this is for you. If you want something as perfect as you would expect from a show car, look elsewhere. On the side of the nut is a stamp of its size. It's not very deep there, so while it's noticeable up close, it's not that noticeable from afar. This mark is only on one side. This means there are 5 sides that are simply flat with no markings. I like the fact that they are solid nuts and not caps. If you don't know the difference, solid ones are one piece while enclosed ones only have chrome to the edge of the flared base or 60 degree base. Caps are also just caps, meaning they have a chrome cap on the standard nut. The ones with lids are more likely to rub off, are easier to dent, and since they are made of two parts, there may be corrosion or other things between the layers. When this happens, the outer layer can expand and make it difficult, if not impossible, to mount a socket or bushing on it. It makes such chrome better. I tried them on a bobby pin I had here and they were very easy to put on and take off. The threads look good too. I'd say I'd give the threads about a 9 out of 10. They use a standard head size, 3/4" or 19mm. I say or because 3/4" and 19mm are very close. So close that the difference between them is less than 0.002 inch. 19 mm equals 0.748031 inches. I can't say I've installed these in my car yet because. they will be sent back. Not because they are faulty but because I bought them from an Amazon warehouse and the kit was supposed to contain 32 nuts but they only sent 22. If they had sent me 32, as they were supposed to, I would have kept them. All in all, these nuts aren't perfect, but they're better than many alternatives. They're cheap too. at a current price of 20, - the piece costs about 65 cents, which is quite cheap for a chrome-plated solid nut. That's why I didn't deduct a single star because they lacked a perfect finish. After all, as they say, you get what you pay for. You buy cheap and have to reckon with some disadvantages. As long as the quality of the materials matches theirs, I have no complaints. They still look way better than what was on my car. I am including some photos so you can see the print from one side and their size and get a better idea of how they look and are made. I hope they help you make the best choice whether they are right for you or not.
