Circuit Performance Tuner Key Acorn ラグナット クロム 12x1.5 鍛造スチール (24個 + ツール)

Just what I was looking for. High quality and good price. I dislike the look of standard “tuner lugs” these have a clean appearance and fit just as well. Most splined lugs can be removed by a thief with a standard socket, the hex adds a bit of security without the hassle of keeping track of a special key. They are steel and have a lot of material around the bore. The specs in the description are totally accurate. I trust them to keep the wheels on the hub 100p.

Awesome product, came on time. Very happy with the quality

UPDATE: I'm downgrading from 3 stars to 1 star. I'd give them zero stars if it were an option. After finally solving a vibration, I discovered these lugnuts are junk. Basically, the conical seat of the lugnuts is not concentric to the threads - which means these lugnuts are incapable of holding a wheel concentric to the hub. This results in vibrations. Here's the longer story for those interested: I ordered a nice set of vintage OZ wheels for my big, vintage Lexus sedan. Mind you, the car rode smoother than silk with its original wheels. Unfortunately, the OZ wheels are rare so I was not able to get them in the exact offset I needed, so I also bought a set of 10mm wheel spacers. I also bought a set of ARP extended wheel studs. When the wheels arrived, I had Discount Tire inspect and spin them to ensure they were nice and straight. They were. I ensured my wheel spacers fit the snout of my hubs just right. They did. I had Michelin Pilot Sports mounted, and fit the wheels to the car. Above 60mph, there was a very obvious vibration. Took the car to the tire shop and they re-checked the wheels/tires - which spun beautifully on the balance machine and were nicely balanced. Next, I thought maybe it was because I didn't use hubrings on the installation. Personally, I think these are usually a gimmick if you have tapered-lug wheels and nuts. A cone has no choice but to fit into another cone concentrically. Five conical lugnuts fitting into 5 conical seats will ensure the wheel is clamped to the hub concentric to the bolt circle of the wheelstuds in the hub....BUT ONLY IF THE CONE OF THE LUGNUTS IS CONCENTRIC TO THE THREADS OF THE LUGNUT! Anyway, I went ahead and bought a set of hubrings to hopefully solve the vibration. Mind you, the OZ wheels have an oddball size hub bore, so I had to custom order the rings. When I installed them, it helped the vibration quite a bit - but did NOT solve it. So I pondered that for awhile when it occurred to me I noticed the lugnuts wobbling as I was running them down onto the wheelstuds - suggesting the outer diameter of the lugnuts was NOT concentric to the inner thread...so maybe the conical taper on the lugnuts was also NOT concentric to the thread - meaning as you torque the nut - it pulls the wheel off-center. So I removed a few of the nuts and mounted them onto an arbor in the chuck of my lathe. I indicated the arbor to ensure it was running true within 0.0005", and mounted the lugnuts onto the arbor - then indicated the conical taper of the lugnuts. I only bothered to measure 3 of the nuts because I was getting readings of over 0.02" run-out. That's absolutely unacceptable. so I ordered a new set of lug nuts, which were more expensive (and much more nicely made) than these Circuit Performance units. I again checked them for run-out before installing and found them to run nice and true. I installed the new, good lugnuts (without hubrings), and VOILA - vibration solved. These Circuit Performance lugnuts cost me dozens of hours of hassle and months of vibrations in my car. They are JUNK. Ok, so here is my original review (when I gave 3 stars), pointing out some of the other issues: Circuit Racing should be absolutely ashamed of themselves for the hex key "tool" they include with this set. It's garbage; it fits the lug nuts sloppy AF. A decent quality 12mm hex key "socket" fits the lugs quite nicely - so I highly, highly recommend you buy one instead of using the included tool. The chrome plating is mediocre. It'll develop rust freckles the first time they get wet. Don't get me wrong, it's better than bare steel or even black oxide - but it's not even as good as the chrome plating on a harbor freight socket. So there's that. Otherwise, they fit, function and torque up just fine. The thread fit was good - I am using these on high quality ARP wheel studs.

they hold my wheels on but the powder coat inside is super cheap and they're rusting in the first month. should have anodized or used stainless.

You get what you pay for, but for the value I'll say that they're great so far! The only thing I have noticed is that the lock key and edges of nuts finish came off after a few uses. Great to start with or on a budget
