In China. We torture tested these lug nuts with over 100 torques at full impact way over the torque spec until the stock stud broke. We're very happy with the quality and feel comfortable putting our name on them.

For what it's worth. I've been running these for a little over a year with probably a dozen wheel changes (track to street wheels). Using ARP on my SKF hubs and stock bolts on my stockers and haven't had a single issue with the lugs. Just make sure you re-torque them after a couple laps. Very happy with the product, also they are disturbingly light.

I'm at a season and a half with your lug nuts and they're fine. (knock on wood)

I need another set just to have on hand tho.

I am the guy (when these originally came out) who asked how many seasons will they last. Well it was a dumb question for obvious reasons, a "season" for one guy is 4 events, for me it's closer to 40.

Anyway I'm on my 5th year with these and there are zero issues. My only "complaint" if you want to call it that, is that it's hard to find impact rated 12 point sockets. If I can pass a tip on to Jason (we talked a couple of times) is to offer ONE 1/2 inch drive impact socket with a set of 20 nuts. Charge a little or even make it free. I think you'd be pleasantly surprised at the response (sales).

Don't forget if you do this send me a couple (they get lost), I'm still using non impact.

Froggy.

lol yah a seaon for me is the entirity of the NASA Texas region, a ton of member days and HPDE's.

My stupid impact socket for these nuts is ridiculous, hardware stores don't carry it. I forgot it one event and ran cycled out **** tires for the weekend because I couldn't change wheels. (to far to drive home and not enough time to order a new socket, local stores had none and nobody not retarded uses 12 point at the track.

Hah, the socket issue is one of my big hangups too. I currently have splined nuts on my wheels and I want to get rid of them because I hate having a non-standard socket.

I just use a non-impact on my Milwaukee electric impact. Worst case, i ruin the socket and replace it. Not difficult or expensive to keep a couple sockets on hand. Again, I've used it hundreds of times without issue.

Me too, but it just seems wrong. I'd like to just use the air impact I use on everything else, not worry if my battery impact has the juice to get through a day, just sayin.

I just picked up something like this off Amazon:
https://www.amazon.com/Sunex-267217-2-Inch-12-Point-Impact/dp/B006L238FA/ref=sr_1_6?ie=UTF8&qid=1549389893&sr=8-6&keywords=17mm+socket+1+2+drive https://www.amazon.com/Sunex-267217-2-Inch-12-Point-Impact/dp/B006L238FA/ref=sr_1_6?ie=UTF8&qid=1549389893&sr=8-6&keywords=17mm+socket+1+2+drive



I've been using it for a long time now.

Picture?

Any chance they were gunned on & not hand started?

Just looking for info as I use these 4 seasons no issue, always hand started.

I've had track support a handful of times or a friend help with wheel changes here and there, so "maybe" I generally hand start them and then gun them down.

im traveling for work so don't have them any but i kept them ill snap a pic when i get a chance.

Thank you.
WIKI INFO below

It is significantly stronger than the most commonly used grades of steel. As others have noted, the strongest known alloy steels in their strongest tempers are stronger than the strongest titanium
alloys in their hardest temper. ... As others have pointed out, Titanium is remarkable for its strength, given its weight.

My experience with most cheap lugs is that they fail before the stud. I imagine the Vette studs are a "good" grade steel but probably not as good as ARP's. It woud be interesting if KATECH could chime in to provide the actual hardness number (such as 200,000 psi tensile strength) if they have it. It had to have been specified to the company that made the lugs that KATECH sells.

Here are some for ARP studs made for NASCAR

ARP Wheel Studs - heat-treated 8740 chrome moly, tensile strength of 200,000 psi, sold in 4 or 5 packs, cadmium plated for extra durability, nuts not included

NASCAR Speed Studs - heat-treated 200,000 psi chrome moly steel, precision J-form threads (formed after heat-treat for improved fatigue strength), nut-starter and bullet shape radius, shot-peened, baked-on dry film lubricant, and double magnaflux inspection, fits the registers of all popular hubs without grinding

NASCAR Speed Nuts - profiled nut face for easy installation, quicker socket releases and resistance to jamming, heat-treated chrome moly, nominally rated at 200,000 psi tensile strength, shot-peened, double magnafluxed, coated with Alumotef III

The lugs are made from Grade 5 6AL-4V titanium which has a tensile strength of about 170,000psi.

We torture tested the lug nuts with 100+ impact torques well above the torque spec until the OEM stud failed. There was no structural damage to the lug or threads. The conical seat had some expected wear and tear due to the harsh impacting.

Thanks Jason, you are an asset to the forum, no doubt. That info backs up my field experience (4 yr/2xmo=about 100 guns on/off) of NO VISIBLE WEAR. I lube the contact faces (cone face) so I also have zero galling. Would have spent 20x4=80 lugsx $2.50 avg cost=$200 on yearly lug replacement, not to mention lowering rotating mass. Guys this is a no brainer if you are a racer/competitor.
