Sometimes there are errors in Vendor catalogs and terminal program listings that go un-noticed.
The computer system at the stores are built and furnished by other services. Errors and omissions happen by the one who does the program entries and don't know better..
The large bulge diameter it to be sure the wheel does not pull off over the Lug Nut, in rough off road use.
Car/ Road only wheels are not normally used off road hence the smaller diameter Lug Nuts..
I used Dorman Nuts and was very expensive in my opinion, but correct.
Believe it or not, there are very heavy specifications for building wheels for public use to minimize failure and liability, excluding accident causes etc.
Good luck.

 

If you go to Mcgards website no where is it claimed they use stainless steel in their lugnuts, Summit just added that. Stainless Steel is too soft for lugnuts, you can find no rust stainless steel lugnuts but they have a steel cap kind of reverse of what the factory two piece Ford lugnuts have.

These indeed fit but what they don't mention is that the are not for OEM wheels. This discussion has been debated on here but there is really nothing to debate. There are other threads on hear that you can search for and is full of interesting readings. Many pictures of the inner OEM wheel openings with the wrong bulge size that some believe is ok because the lugs stated they fit the vehicle you are looking for on some website. Even most reps that work at these businesses when people have called don't know the difference and say "yes they fit". If you look here: https://www.cjponyparts.com/gorilla-...or/p/WHLLN123/ Scroll to the bottom and it will say they are for OEM wheels only and not for aftermarket wheels. Picture is misleading, I ordered from here and they were correct in the past. Hope this helps.[/QUOTE]
Thanks again for the help. When I look at reviews, I'm seeing far more that mention rust on the Gorilla brand.
I should get the 64073 from Summitracing tomorrow. I'll let you know how they measure up. The search tools on SummitRacing and MCGARD are fairly extensive. This is the tile that applies to our truck.

 

Update. I received the new 64073 McGard nuts. They are definitely a different size. I called McGard and they verified that they are for my OEM wheels. I sent SummitRacing an email asking for confirmation.Looking them over, they seem to be smaller than the OEM Ford lug nuts for our 2022 F150 Platinum.I do understand that the OEM lug wrench will not fit, as the OEM socket size is 13/16" while the McGard 64703 is 22mm. And they are not to be used on steel wheels. Our wheels are the OEM 20" polished aluminum wheels, standard on the Platinum Group 701A.

Should I be concerned that the 64073 will damage the OEM wheel?

I would be very interested in the measurements of the Gorilla 61148FS or the 61148FSBC

 

Yes. I knew McGuard would say they are correct. If you send them a picture they will say they look identical, even a blind person can see that enormous difference. In post #10 I mentioned the incompetence on this subject. Sure they fit, but not sized correctly for OEM wheels. Factory bulge is what you need. I would not put them on and trust my life with them. I can turn those lug nuts until they come out the back side of the wheel with less torque than you think. Think about it, if you were replacing a broken wheel lug, would you install one that was half the size? No.

 

Now this opinion may not be exactly what you are looking for but, I think the 60 deg angle is what locates the truck wheel, and if you inspect the contact marks on a stock wheel nut you will see it only contacts so far up the angle.
I think most of the damage comes from tire folk with the wrong size worn sockets and impact guns over time. If the wheel is located and zipped on with low torque then finished by hand, the chance of damage to the wheel and nuts will/should be minimal even by careless operators.
I watched a tire guy destroy one of my lock nuts before I stopped him and requested he use a bar by hand to loosen the locknut, the impact was vibrating and bouncing on the surface as they were using the battery style impacts. My mistake, should have taken the locks off myself before I went there, lesson learned.

If the concern is about the size of the bulge above the taper, then why not just get new factory OEM nuts, they should last a few years anyway, really not much cost over time for peace of mind.

 

I'm most concerned about Ford or Discount Tire doing some damage to the OEM that I do not discover until changing the tire on the road. And finding that the lug wrench will not fit the damaged nut.
