any input anybody on how to remove a stripped "spline" lug nut that needs a key to take off?

I overtightened it and the lug completely stripped inside. I sprayed some wd-40, took an oversized socket and tried hammering it in.... it didn't budge. Cutting it out would be my last resort, anybody have any other ideas?

 

Most tire shops have a rig to remove them .. just be careful they might damage the wheel a bit.

 

Ouch, did not know a Spline Lug could be stripped. Are they the McGard Spline Lugs?

yea the threads inside are completely stripped. Bought these lugs on ebay, forgot what brand it was but it began w/ a "K" and japan made. Anyways, got the stripped lug out w/ out any damage to the wheel. Just went to sears and picked a really thick allen key and it just came out. So all is good
