I am looking for a one-piece lug nut to replace the two-piece factory style lug nut. The application is for a 2008 Toyota Camry which uses part Toyota Part #90084-94001 or Dorman Part #611-211. Basically, it is a mag-seat style lug nut w/washer that uses M12x1.5 threads.

The issue with the factory two-piece lug nut design is that overtime, the outer chrome cap will "swell" and this makes removal with a 21mm (or even 21.5mm) socket to be difficult or impossible.

So far, the only one-piece design lug nuts that I have found are:

1) Gorilla 73137TB or 73138T. These are either $5/ea (pack of 4) or $1.57/ea (if I buy 60).

2) DPAccessories LCM3C6HCOCH04020. These are $39 for a 20-pack.

Both of these options are a hair longer than the factory ones but I think that is a non-issue.

Does anyone know of any other options?

Thanks!

I have the same lugnut for my 2009 Venza. I do use steel wheels and they take a one piece acorn style lugnut. And those are pretty beat up with rust with all the salt we use on the roads.
The stock ones are used for the summer with the stock wheels, and those are still in perfect condition after 10 years.
Why are your driving conditions causing issues with the stock lugnut? You are in the desert. Curious here.
 
Same design on my Tundra - the truck sees a lot of salt (tidal flooding, and then I drive it up in snow country) and my 2 year old lug nuts are already corroding. I've cleaned them up on a wire wheel, hit them with zinc primer. As a hedge against future issues, I bought a complete set of 20 lightly used lug nuts on eBay for $40. They were take-offs from a new Tundra that got custom wheels.

Anyway, I'm having trouble with Toyota's lug nuts, too. For the flat alloy wheels design, I couldn't find anything....well, anything of quality. Lots of cheap off shore junk for the alloy/flat washer design. There are tons of replacements for the conical seat steel wheel design.

I am very interested in what you find and select, because I couldn't find anything beyond factory...

The driving conditions have nothing to do with it. What happens is when you take your vehicle into the dealer or tire service center, and they use an air impact tool to remove / replace the lug nuts. (Which most all of them do). If their socket doesn't fit correctly, it ends up deforming the soft sheet metal covers on the nuts, and you can no longer get the proper size socket or lug wrench on them.

I had this happen on my 1991 Ford F-150 that came equipped from the factory with these sheet metal covered lug nuts. (The auto makers have been using these things for decades). I have even had the covers themselves come completely off, exposing the standard steel lug nut underneath. Which is then too small to properly fit the lug wrench provided with the vehicle. This can cause you to round off, and or strip the flats on the smaller nut, leaving you stranded, with no way to remove the damaged nut. That will end up forcing you to call for roadside assistance to change out a simple flat.

All it takes is one exposure to an impact tool to cause any or all of this. That's why I didn't wait for it to happen with my new Toyota. I simply replaced all of them with heavily Chrome plated one piece lug nuts. Problem solved before it grows into a larger one.

The one's I purchased are advertised as being triple chrome plated. The plating seems to be very heavy. I was going to purchase a similar type from Gorilla Automotive. But after reading the reviews, many were complaining of rusting issues. I'm not that concerned about rust or corrosion out here in the desert, but it swayed me to the DP Accessories nuts. Which received better reviews.

After I installed them I checked to make sure the stock, supplied lug wrench that came with the car, fit all of them. It did. This is something you want to be sure to check in your driveway. Not at night on the side of the road. And be sure to check every lug nut on the vehicle. Because the plating can vary from nut to nut, depending on how long they leave them in the plating tank. The buildup can vary enough to cause issues on a tight fitting lug wrench.

Ok, makes sense. I do all my servicing including brake work, and seasonal wheel swaps.
Even though I have an impact gun, i use the old school cross wrench for the lug nuts and a torque wrench for the final in 2 steps.
 
The only thing that makes 2 piece lug nuts "swell" is the hammering of an impact wrench to break the nut loose from the initial torque. Suggestion: use a 21mm socket on a breaker bar.
 
The lug bolts on the 2014+ cherokee also are 2 piece..

The worst ones I ever had were on ford focus 2005 and 2007.. I carried 2 sockets for both of those cars... 18mm and 19mm IIRC.

I had about half of each size within a couple years.. and that was with me doing most of the work and no impact tools.
 
Not a Toyota, but the same principle with my Ram 1500. I bought a set of machined one piece black lug nuts off eBay for cheap. They do form a tiny bit of rust on the hex edges where they are stressed from a socket, but so far so good.

McGards would be about the best you could get.

Gorillas would be 2nd.

I could buy that. I don't know what kind of abuse my vehicles got at the dealer, but it wasn't for long. The lugs seem fine on my three Toyota's, and I do think they have that sheetmetal cover also. I don't often use the impact to remove lugs, certainly not install.
 
Had the same problem on my pickup, just took the shell off and now use a 13/16" socket instead of 19 mm. Very minimal rust if any in 3 years since I've done it and l live in the salt belt.
 
I'm having that problem as well on 2 family vehicles. I take the Amazon reviews with a grain of salt, but there are complaints with pics showing the solid metal lugnuts rusting out. In the snow belt thats a concern.
