If the nuts aren't recessed it's a piece of piss. If getting a smaller socket and bashing the twunt on doesn't work a cold chisel and a FBH should shift it unless it's been overtightened.
This advice comes from the man who left the adaptor on a wheelnut and saw it bounce off and go 30 feet in the air on the M62. If you were on the M62 about 5 years ago and a metal blob bounced off a Sierra and took out your screen I apologise.
