Frigged Lug Nut

I finally got a replacement set of lug nuts to take care of the capped ones that have been worked over by myself and various tire shops over the years. One of the old lug nuts is rounded off. I pounded on the 27mm socket. The cap turned, but not the nut itself.

I Dremeled off most of the cap (probably a mistake but as the cap was spinning I didn't know what else to do). Now I've managed to round off the nut itself after hammering on a 1" socket. The nut was probably torqued to God-knows-what ft/lbs by the tire shop.

So what to do now? Drill it on either side of the stud and hammer the shit out of it, hoping that it breaks and just falls off of the stud?

Yes, I know that I'm a moron so save it.:victory:

I would try to air hammer it off. Sharpen a chisel bit and dig it into the side of the rounded off nut then hit it from the side to turn it iff the stud

If it's that bad, you're likely gonna be welding a nut to it and hoping the heat breaks it loose.

This is what I would do next.

If that doesn't work I would go to a cutoff wheel and split the stud/nut and break the nut off with a chisel.

it's slow work, but you can use a file and put some flats back on the nut until you can fit a 6 pt. 15/16" socket or whatever (not sure what size it's at now). Don't use a 12 pt. socket. Also make sure the vehicle's weight isn't pushing the stud on the wheel you're working on (that it's jacked up -- sort of common sense but sometimes we leave a little weight on the wheel to keep it from spinning right? Make sure it's in the air with the brake on and CD locked etc.) When you're done, brush some anti-seize on all your studs and lug nut threads.

Usually when there that bad I just get a 28NM socket and hammer it on. Offcourse that's when the cap is still on. I would find a socket that will hammer on then use a big breaker bar and break it slowly

Before you try any further socket, do this.
Heat the lug nut with a torch, then spray the snot out of it with PB Blaster. Tap on the end of it with a hammer. Repeat this process 2-3 times. THEN try your socket. I've broken loose many seized up nuts this way.

I finally got around to trying that. It worked like a charm. Thanks!
