Has anyone ever had to replace one of these?

Its a cambelt tensioner stud from an AAZ 1996 1.9td which is in my T25.
Had to do the head gasket, and as I was setting the timing, I could feel the threads pulling. As you can see the M8 threads have partially stripped on the end, so I need another one.
I've checked Brickwerks but it looks like they don't stock them. I'm guessing they are dealer only unless you can tell me different.
Cheers
