i bought a set of Wurth manifold bolts a month or so ago and finally got around to doing it after getting the manifold skimmed.
The came with copper lock nuts and I found when fitting that all of the ends of the threads were stripped a bit by the copper nuts. One stripped the threads before it had even got to 25nm and then the stud snapped when it was undone.
I have read everywhere how great these studs are so is it likely I've just bought some cheap Chinese s**t that's being sold as Wurth?
