Really easy question: what size are Mazda lug nuts?

Nothing to do with racing or competition, but I know you guys, so hopefully someone will answer this before the thread gets moved.

What size socket do I need to remove Mazda lug nuts? 17 mm?

Thanks,
Steve

13/16 is too small if 21mm is the size.

21mm = .8267 inches
13/16"= .8125 inches

21mm- 13/16" M12 x 1.5 threads

could be wrong though since we run the smaller SSR nuts, I think they're 19mm though

Thanks guys! (Well, except for Dshiznit1489.) I'm helping a non-car savvy friend swap a set of wheels, and I wanted to know what size socket to get since I don't have a Mazda myself.

Well typical lug nut sizes (for cars) I've seen in my limited experience tend to either be 19mm/3/4" (very nearly the same size) or 21mm. Figure carry those two in most unknown cases and you'd be good.

F*cking Mazda cheap-a$$ factory lug nuts.

Throw them all out and get good ones.

Yeah, I guess I could. Someone may need to watch over my shoulder to be sure that I don't neglect to cover torquing them down after day 1 impound in Topeka.

It's 13/16th, I didn't have a 21 so I tried that and it works. I changed mine all to aftermarket 19MM though.

Have you ever tried using a little anti-seize on your lug studs?

at least throw out the keyed ones and buy decent ones. my keyed lugs AND the key itself both stripped.

NOT fun having to pound that thing out of there ...

Anti-seize may help with the OE nuts, but it's not a solution. The OE nuts are fine for a production car that probably won't have more than a dozen wheel change cycles in its life. But they will still gall the studs eventually when you do 40 cycles a year or more. They come brand new with all kinds of grit and shavings inside. Anti-seize provides some lubrication to get around that, but it also acts like glue, attracting and grabbing new slivers and additional grit.

Try screwing an OE lugnut onto a new stud and then try it with a quality aftermarket part. Try it both with and an without anti-seize. The difference that you can feel is quite stunning.

Why live with the problem when you can do away with it for $50 or so?

13/16 for my super original 2004. I use the spark plug deep socket with the rubber insert. Find what works best for you though, get creative, stay safe and protect the parts of your car aka don't be lazy and ruin it. Just like jacking the 8s up make a jig and do the happy dance that you did it right

I'm pretty certain that the OP figured it out in the 5+ years separating the last post and yours.

Yah, but I didn't really want to ramp the snark up too quickly. Figure we can all get in on the action and give it a simple, linear progression.
