After a bit of advice chaps and chappesses,

Just on my way home when I heard a short clatter from the engine bay, thought nothing of it then the battery light came on and the steering went into muscle-man mode!

I assumed that the belt had snapped so drove home and on popping the lid found the centre bolt for tensioner had snapped just inside the mount. I managed to drill the old one out fairly easy so need to replace it (and the belt to be on the safe side as it was half rubbing on the remaining pulleys so is probably pooped)

I have a feeling I may have overtightened the bolt when I replaced the idler pulley bearing a few weeks ago so more than likely my bad!

I was wondering where is the best place to get one, or can I use a standard 8.8 bolt, I haven't checked yet, but it looks like it's an M10 thread. So will an 8.8 do the job? It's not monstrous torque so I thought it would be OK.

Any help/advice appreciated guys.

Got the britpart part number?

Googling that will tell you all you need to know.

If its m10 maybe a 12.9 bolt is the best option?

Couldn't find any specs online only adverts for the part. Ended up getting one of the Bay so at least I know it's the right part.

Thanks for the replies.
