I was checking torque on my MKC, got one new tire so decided to check all, and one of the lugs was screwed up. It was not on the new tire so who knows when it was done, I got it with 26,000 miles on it. My questions:
1. What is the best way to get the damaged lug off? I tried to smooth out the edges and think I have it where I could drive a 19MM socket on in case I have a flat but would only do that in an emergency.
2. What is a good lug, manufacturer and part #, to replace the OEMs with and how do I make sure it is a one piece and sturdy? I see a lot of them on Amazon but want to make sure I get a good one.

I am not sure what the age and miles you have, but I would take it to the dealership. it should be covered under warranty.

Mine were replaced this spring under warranty when my dealer changed my winter tires to all-seasons.

If there is no telling when or why it happened I doubt if it would be under warranty. Plus I would not want to put OEM lugs back on it.
I saw some McGard and DP brands that are one piece.

Wife does not want any thing different looking so I may go with the McGard or DP. It says they fit the MKC but how do I make sure?

Most of what I am finding are a bit longer than OEM. I did find PTC 98260 at Rockauto, looks to be the same size but I can't find if it is one piece or just like the OEM. Does anybody know?

If you want to be absolutely sure - go to the lincoln.com website and look up the HTML version of your owner manual. Go to the WHEEL LUG NUT TORQUE SPECIFICATIONS entry (you can search for that phrase and go directly to it). The fitment for lug nuts is according to the size of the bolt and the pitch of the threads. My 2015 for example specifies an M12x1.5 lug nut. My guess is many MKC units are similar. The manual will have your exact spec. This may or may not help you at rockauto as they are mostly concerned about a part number for reference, but under the product description it should have some information about bolt size and thread pitch - which tells the tale.

Looking at the PTC lug offered up for my 2015 they are the same two piece design as the original. I would shop amazon and look for a verified solid one piece lug design that is as low profile as you can get. Lots of options there for a reasonable price.

The lug nuts I referenced in previous post were very close to the same as the OEM dimension wise. They look like a quality lug nut, much better than the OEMs. I got the really bad one off by driving a 12 point 3/4" deep socket on it and used a breaker bar with a cheater to break it lose, thanks YouTube. I would say 75% of the original nuts showed signs of wear, probably from tire rotation before I got the vehicle. Why would Lincoln/Ford use such crappy materials? They know that people change and rotate tires as a normal maintenance. For a few bucks more, I bet their cost would have been $5 if that, they could have minimized this common problem.

It’s not just Ford, many manufacturers use the same setup including my Jeep Wrangler.

Makes you wonder why that design is so prevalent across manufacturers. What kind of engineer decided to put soft metal where it will come into contact with hardened steel tools; lug wrenches, impact tools, etc? They are probably now working in D.C.

It’s all about corrosion. It’s a polished aluminum cap. If it were chromed steel the first time you hit them with impact wrenches they start to rust. At one time and maybe even now Porsche’s uses polished steel lugs but the mechanics had hardened plastic lined sockets to prevent damage.

So we have to chose corrosion or misshapened lug nuts. With 30k miles figure the tires have been rotated 5 times give or take and a majority of the lug nuts showed damage. Guess they go for looks instead of practicality.

My take on it is that they went for saving about $50 all around on a set of lugs. The OEM lugs are just cheap. They look good when new, but because of the way they are made (cheaply) they have low longevity - especially in northern climates.

If you live in a warm climate the lugs are fine they don’t swell from the salt first led moisture and freezing temperatures. In 4 years I’ve lost one to swelling. Otherwise the dealer rotates my tires twice a year with the proper socket with no issues.

The real issue is that unless you carry the proper tools with you as a matter of course - these lugs can leave you stranded if even one goes bad and you cannot get the supplied oem lug wrench over the nut. I call that a problem that should not have occurred on a vehicle at this (or any) price point.
