Good buy
2000 Honda CR-V. Direct replacement. Very durable, they fit Hondas. Easy to install and remove, thread quality so far is great. Paint chipping is minimal but I fear overtime they will chip alot allowing rust to set in

These Lug Nuts Gripped My Wheels Like Their Lives Depended on It
I bought the AUTOPTIM M12x1.25 spline lug nuts as replacements for my worn-out factory ones, and let me tell you — these things clamp onto your wheels with the enthusiasm of a golden retriever greeting you at the door. Fitment: Threaded on perfectly. No cross-threading, no sketchy wiggle, no wondering if I was one torque click away from disaster. They fit my studs like they were custom made for them. Finish & Build: The black coating looks clean and actually stays black. I’ve hit some Florida rain, a couple muddy backroads, and one questionable car wash, and they still look brand new. No chipping, no rust, no “oh great, now they’re brown” surprises. Spline Key: The included spline tool fits nicely and gives you that satisfying “locked in” feeling. If someone wants to steal your wheels, they’re either going to need the exact key… or way too much free time. Performance: Tightened down solid. Zero loosening, zero drama. I’ve driven highway, backroads, speed bumps that were definitely too tall, and one pothole that could have been a portal to another dimension — these lug nuts did not care. Not even a shake. Final Thoughts: These are affordable, sturdy, and look way better than the factory ones. If you want lug nuts that grip, don’t rust, and make your wheels look like they hit the gym — these are the ones. Highly recommend. 10/10. Would let them secure my wheels (and possibly my life) again.

Short, but works fine on tacoma.
They are steel. They are pretty short. Maybe the shortest possible and still be usable for a truck. But they work fine. The coating is fine. Not the best, not the worst. So far they're still black. I'd buy them.again for the price. Came with 6 per wheel. Only use on aftermarket wheels. Not the stock ones.

Good plating.
I bought the black and the finish was nice! I'm in Maine and the finish holds up to the mess the put on the roads that eats metal.

Faded
Looked good out the box but paint faded after 5 months, it looks like a faded matt color. Powder coating is the way to go

Wonderful upgrade. Standard spline works a lot better than horrible chrome capped lug nuts. Needed them for my Tacoma rims that require a splined lug as they are thinner than regular lug nuts and you won’t damage your rim putting them on.

Produit relativement cher (prix) mais conforme. Je ne pense pas que le revêtement peinture résiste longtemps : après un premier montage cette dernière est déjà parti sur la douille.

I bought these for my 2022 Nissan Frontier Pro 4x. I have 6 lug nuts per wheel and this brand is the only one I was able to find(the only one that looked like they were good quality anyway)that had a set of 24 lug nuts in a set! They came really well packaged and the lug nuts fit perfectly and the black coating on them looks really good too. Hopefully they last for a while.
