Not standard 1.0 pitch. Though you may have them.

I tried a M6x15x1.0 pitch and I can't get more than 1 turn. Am I wrong that this is a special bolt? Amyone have a spec?

I just measured one of mine, it's M6x18x1.0. Chase the threads!

Thanks, I'll do that. I just didn't want to f' up a nut that was welded to the car.

Next time just drop me a pm, I'll notice it sooner.

John should be right on the thread/pitch/length. Beware of rust & previous owners.

You know what? I try to get one out over Christmas just to see what the pitch is.

I did pull out the tap and do these as well as the ones on the decklid itself. I just didn't want to force it as they can't be replaced easliy.
