A tire shop i use broke so many of those the store stopped honoring the warranty. He is dirt cheap on everything he does there and you can tell by the sound of the impacts he has the compressors turned WAY up so that probably had a lot to do with it.One of the well known members here blew up the Koken extended version and got the run around about warranty on it too.
As I stated previously, consider all these consumables, especially if used heavily. Some of mine have a 400ftlb max torque warning etched on them.
I don't normally recommend HF but the lifetime warranty might save some hassle and the Pittsburgh Pro set comes recommended.

It is worth mentioning that he said the SO and Matco reps also refuse to warranty his tools...
This reminds me I need to look at the set I bought at Menards. I swear the one I used on my truck was slipping around the lug nut.. almost like it stretched.
I put it back in the box and grabbed a regular impact socket. I forget about taking a closer look at them.

I ignore manufacturer instructions and put anti-seize compound on my lug nuts, under them, and between the wheel and the hub.
I’d have to think about this, could be wrong, but I think a 1400ftlb impact gun doesn’t deliver 1400ftlbs the second you pull the trigger. So if your lugs will come off with, let’s say 200ftlbs of reverse torque, I think that’s all they’ll see ish.
Now I DO believe the initial trigger pull of a 1000ftlbs gun delivers more wallop than a 500ftlbs gun.
Last, as I’ve written recently, I think thin walled impacts perform worse than heavy wall impacts. I think they don’t deliver as much torque and are more prone to cracking, though I’d have to think about exactly why that’s true.
So here are my thoughts for you:

So here are my thoughts for you:
- If you don’t lube your lugs, you might need more torque to remove them than a thin walled socket was designed for.
- When you know a bolt isn’t frozen, and you want to use thin walled sockets or chrome ones, use a lower torque gun. The monster guns really aren’t a great idea for all the time use. That said, I don’t believe a single burp or two delivers their max torque.
Pretty sure a greater wall thickness of ANYTHING is stronger and less prone to cracks, all else equal.
This goes for sockets, engine blocks, exhaust headers, connecting rods, the plywood under your roof….
Key word…. ALL ELSE EQUAL

How about these Snap-on sockets designed for lug nuts? There's no plastic sleeve but just take your time and don't hit the wheels...

Anti-seize has to change suggested torque value spec’s? Someone smarter than me will know better.
Snap on is pretty good about describing the application. In this case it says:How about these Snap-on sockets designed for lug nuts? There's no plastic sleeve but just take your time and don't hit the wheels...

- Deeper hex geometry allows socket to fit further onto lug nuts, making them less likely to damage or break decorative caps
- Saves technician time and helps prevent potential customer complaints from marred or damaged caps
This is a long story involving the definition of "dry torque". Long story short, I apply anti-sieze and don't change the torque spec. On paper, I'm over stretching the lug bolts. In reality, I'm probably closer to factory "dry torque".

It absolutely does and is generally not recommended for wheel lugnuts/bolts.
For standard bolt wet/dry torque values, charts are available.
A 15-25% reduction for lubricated fasteners is a common range, but manufacturer specifications vary and should be followed.
The problem is "dry torque" values are based on clean, lightly oiled or dry film lubed hardware, contrary to popular opinion. "Wet torque" is based on greases and sealants applied at the time of installation. My industry developed the science for this 75 yrs ago along with the numbers most industries now use. Since then, we've continued to test. We strain gage hardware to calculate the friction that consumes a high percentage of the torque we apply.
Used car lugs are often chalky, corroded, gritty, grimy and smearing anti sieze on them doesn't make that go away. The Kia's lugs were so bad, we snapped one removing one of the lug nuts last weekend. And the lugs on Kias trap the plastic wheel covers, so heat wasn't an option (or at least not a torch and that's all I had).
More:
Dry, chalky fasteners experience something we call "stick slip". When you apply torque, the static friction is so high, the fastener resists and resists then slips, sometimes resulting in an over torque condition. We tested this for engine mounts. What we found was, for improperly prepared hardware, the average torque (bolt strain) was roughly where we wanted it to be, but the bolt strains varied 5X greater than lubed hardware. So it's not as simple as raising or lowering target torque values to account for the status of the hardware.
You would think the car companies research all this and know what they are doing. Some of my friends at work come from the car industry. 2 I'm thinking of are crash experts, and that's complicated science. So surely they know what they are doing. But I can't square what I know with what I've read from auto manufacturers. The spec above comes from John Deere. Not sure what they know or how they know it.
Please don't do what I do or take this as my professional advice. But here's my thinking for those of you who are intellectually curious:

- I want all the lugs to strain equally. Raybetos published a paper on uneven lug torques being the reason for brake rotor warping. I made a Finite Element Model of a disk brake at work and determined this is possible.
- I don't want to deal with a frozen, corroded lug nut on the side of the road if I need to change a tire.
- Anti-sieze isn't much of a lubricant. It's a barrier, corrosion inhibitor. So I'm not convinced it reduces friction all that much. Especially when applied to an already rough surface.
- I'd rather have over torqued lugs than under torqued lugs. It's possible the "stick" in "stick slip" could result in lower than expected lug torques.
- Torque is kinda junk science. The goal is fastener load and torque is a VERY imperfect measure of that. I guess I feel, FOR AUTOMOTIVE, load similarity is often more important than achieving a specific pre-load.

Its not just about over-torqued lugnuts and wheel bolts. Think about what they are clamping. The steel wheels of yesterday would take a lot of abuse that will damage todays aluminum and magnesium wheels.
Not so sure I am buying the aerospace engineer degree when reading posts like above. Getting burnt out on following specs? Career fatigue? I tease...

So the concern about the wheels would be fatigue. And I’m not sure the number of times off and on would be enough cycles to make a difference.
Up to 80% of the torque we apply to a fastener head is consumed by friction. That number could be higher in certain circumstances. So the accuracy of the torque wrench being 1-2% is completely overshadowed by the possibilty friction could be 80% +/- 10%.
If you don’t want to apply anti-seize, you really should do something to restore the condition of the hardware to its factory new condition inorder to use their torque numbers reliably. At a minimum, threads should be clean, mating surfaces clean and deburred and a light machine oil like 3 in 1 sparingly applied.
None of that is my reality on any of my current vehicles. Moreover, I think a lot of us don’t know what the condition of our lugs is because we remove and install lug nuts with impact guns. I think if you can’t thread a nut on easily by hand, thats too much friction.
From my Ram's FSM:
I will agree the threads need to be in good condition and free of corrosion.

I can't be doing with the mess of anti-seize, I don't use it at all on anything and I've been in this game 40 odd years. If it doesn't come factory installed you don't need it!!!!
In my experience it just attracts grit and brake dust and messes up fasteners/threads/clothing/tool handles.

I’m not sure what we do at work. I can find out. But we would do whatever is best.
Automotive would do whatever was cheapest. It’s sad but I think new car customers in the US hold on to their cars for about 5 yrs. It’s possible those vehicles will only have their wheels off twice in that time. Once for brake pads and once for tires.
So it doesn’t make any sense for the factory to commit any resources or time to solve a problem for some future owner who is not their customer. Automotive really fights for every penny. I wouldn’t read anything into the corners they cut but that.

Keep in mind many wheel studs/bolts already come from the OEM with dry surface treatment to resist rust and corrosion. Could be Dacromet, zinc/yellow zinc, black oxide, phosphate and oil, cadmium, etc. and these coatings each come with different dry lubricity specs factored into torque specs. Multiple R&R cycles will compromise this over time. Wirebrushing will accelerate the removal. Ultimately a replacement non-waxy dry coating would be optimal but those options are limited.

I remember getting into a debate about using anti-seize on spark plugs, turned out the plug manufacturers recommend against it due to heat transfer issues, they also said the special plating on the metal section is adequate if service intervals are observed.
I'm old enough to remember People slathering brake calipers with Coppa-slip and destroying the rubber slide pin boots!!
The only thing I do is use a tiny mist of spray wax on wheel spigots to prevent wheels sticking to the hub. Or a dab of blue "Lock and Seal" where the factory specifies it.
This is what V.A.G recommend to Service Departments (part number superceded to D 322 000 M2).
I doubt it's about money or time, it's more about maintaining a clean/safe factory environment (Manufacturers don't see a lack of proper vehicle maintenance as a problem, they see it as an opportunity to make money
).

The Kia I just did brakes on was a 2016 with 120k miles. The brakes were all rusted. One lug was broken on the drivers side and we broke one on the passenger side (4 lug wheels). Clearly no one put any sort of anything on the lugs, hub, calipers, nothing. Doing nothing is clearly not what engineering intended. Whatever they did at the factory, didn’t hold up and I wouldn't expect it to. I think (obviously) doing nothing is not the right answer.

I’ve had many different sets of lug sockets over the years, but the game changer for me recently was the extended version like below. I’m not sure why all brands aren’t this length to avoid having to use an extension

It’s kind of a **** box, to be honest. I haven’t seen a car that age with that many miles looking so bad in a long time. All our other vehicles are older and in much better shape. My F150 is a 2013 with 205k trouble free miles. It’s my first pick up truck and I’m very impressed by it.It held up for nine years and 120k miles, then KIA want you to buy another one

I value KIA and Hyundai products like I do SAMSUNG, they do a decent enough job for what they cost, but nobody is ever going to restore/cherish them as classic cars, they are more like disposable domestic appliances on wheels!!!

I have had no issues with these.
No, their product description has nothing to do with plastic wheel covers vs. alloy rims.
When they mention "decorative caps" they are talking about OEM lug nuts that are often two-piece (chrome cap over steel).
Interesting. I didn’t get that from the description. I think I’ve never owned a car fancy enough for lug nut covers! Here’s what they said in application:
- For use on lug nuts and wheel studs, specifically beneficial for those with decorative coverings
True. But he was also a pro working at a shop and probably dealing with **** that was just impacted on at 150 lbf-ft by a prior "pro".
Definitely don't expect a warranty on Kokens, or any of these. I've had the 21mm koken for years and it hasn't broken. Now, maybe that's because I hit them with an impact to ~50 lbf-ft and then use a torque wrench. Some shops run them on to 120+ lbf-ft then check with a 90 lbf-ft torque wrench. Click? It's good. And then the next guy breaks a thin socket on them and expects a warranty?
If Snap On doesn't sell these, it's for a reason.

I've chiseled off a few hundred of those. Also had the Snapon 4 socket flip's with half sizes just for those. I was the only tech within 500 miles that used them. LMAO

My lug nut sockets are pretty muttly. Most of my plastic sleeved ones are the old color coded Harbor Freight ones (the small set). I filled in that set with OEM and Grey Pneumatic, since the small HF set was missing a lot of sizes. My flip sockets, that I keep with them, are Grey Pneumatic in a couple different styles. My locking lug nut set is Harbor Freight with a few other brands that I have added over the years.
I don’t want to go out to the cold garage right now, but it would be a safe bet to say that there are other lug nut sockets that I have forgotten. There are also some that I could move from my cart into regular tool boxes… ones in sizes that I haven’t had vehicles that take those sizes in years. My wife’s vintage bread truck was the last vehicle we owned that used 3/4”.
Really, I could pare the ones in the cart down to 19mm and 21mm.

Got it! Haven’t used it yet. But, it is now on hand for the next time I remove my wheels.
I don’t intend to use this on an impact gun. I will use a breaker bar, so it “should” hold
up nicely. Even with a breaker bar I still prefer this type of socket to protect the painted aluminum rims.

I think the Ko-Ken 4300PMZ.65-22 is non-impact, for those looking for that.
If the Titan turns out to not work so well, I will give that a look for sure!
Are all of these plastic covered thin walled sockets non impact? I think my Bluepoint set say non impact.
Does this stop anyone from using these on their impact guns?
Just guessing- if I were designing sockets, I might design my impact sockets for 10^9 cycles. Chrome, I would size for strength, not fatigue.
I personally ignore the warnings and use these all the time on my impact gun. I know eventually they will go bad, and could, possibly shatter. Knowing this, I ALWAYS wear eye pro when using my impact gun. I probably yank tires off cars a dozen times a year. So could be quite a lot of time before I need a new set. But I think those of you using these more often, should splash out on a new set every so often.
Ko-Ken calls the ones with the built in extension "Thin Wall Impact Wheel Nut Sockets" and shows a video of them using an impact on them.

No. They're anodized impact sockets. Sunex has a 15mm and 1" that are clear anodized though.
