I've bought this exact set twice now, for 2 different cars. The first set was purchased in 2017 and that car has been through 5 or 6 sets of tires and countless rotations and brake jobs, repairs/upgrades, etc. The car is still on OEM studs and the lug nuts perform and look brand new. Buy the real deal.

Got the lug nuts, but these don't come with the washer at the end of the lug nut and therefore won't securely fit my SR5 4Runner and therefore will need to return. Can't really say much about the quality or durability on this brand lug nuts

Original bolts were all in horrible condition and these were a perfect replacement in fit and exceptional finish. Well priced that’s for sure so in my book an excellent value of looks, performance, and price!

I finally bought a set of new wheels for my beloved Fit Sport and while doing the research, everyone mentions getting these acorn style lugs for aftermarket wheels. I didn't buy these on first attempt, I bought one of the off brands Amazon insists on pushing to the top of search results. When I tried those, they didn't thread smoothly so immediately back in the box they went. I'm not going to have an older Honda that's missing a lug stem.So I found these, I know the brand and the price was right so I bought them. I wish Gorilla would make these in other colors as well, since I wanted red lugs, but I'm happy with the way these match the gunmetal color of my wheels. Everything else was textbook, they threaded on and continue to do so smoothly and by hand every time, assuring that my lug stems stay intact. The included removal tool provides some additional security and I know I can always get another in case something happens to it.All in all, a great part that just works as it should and compliments my new wheels in a great way. Forget what all the snobs online say about buying a set of lugs for more than $150 when these, for less than $21 fit my needs ideally. You won't be sorry...

First off these are SMALL DIAMETER (21138BC) and considered tuner lug nuts They are not your standard acorn or acorn bulge lug nuts. Please go to Gorillas website and determine:1)which style/seat you have (Acorn, Bulge style acorn, Standard Mag, ect...)2) Determine your thread size3)Know what Hex head you need (13/16, 3/4, ect)Everything you need to learn and know is under lug nuts and reference guides on gorillas Website.I knew my lug nuts were a conical seat acorn style lug nut 12x1.5 and that was not enough info to determine EXACTLY what I could use to replace the OEM lug nuts on my 2021 Trailblazer. Save yourself the trouble of potentially returning these lug nuts by educating yourself before buying. I THOUGHT I knew enough by knowing the above but clearly I did not. I gave this seller and product a 5 star rating as it's not the sellers fault I didn't know the difference between tuner S/D lug nuts acorn style and bulge acorn style.

Exactly as described, used on BMW e60 5 Series with wide deep dish rims and slightly smaller lug holes requiring a slim longer nut and tool.These worked perfectly for my needs, I have purchased these before and used them on another car for over 9 years without issues, i hope to have the same luck with these.They were paired with extended stud conversion kit and are work perfectly.Highly recommend them to anybody, even if it is to replace your existing nuts

I bought these for a set of Work Meister S1 wheels and so far like them. The lugs are impressively small and have a snug fitting key adapter. I have used a number of lugs before and these are probably the smallest I have seen. The diameter of the the outside of the lug (with the key on) is no bigger than the diameter of the 60 degree lug seat. This means it should theoretically fit in even the tightest tolerance wheels.These are spline drive lugs, so a standard lug wrench won't get them off. This likely provides a small degree of security by itself, though for expensive wheels I would recommend a good set of locks. I picked up the . The finish will likely hold up well over time. This is due to the nature of the finish itself and the fact that the key fits very precisely and will not slip across the splines. I find that one of the main reasons regular hex lugs get scratched is ill-fitting wrenches which slip and slide across the surface of the lug. You will get none of that with these lugs.The key for the lugs has a section for a 3/4" wrench and one for a 13/16" wrench. I would suggest using the 13/16" since it is closer to the middle of the key, and is a larger diameter. This will put less stress on the key itself, reducing wear over time.Overall a very well designed set of lugs for tuner wheels.
