I wouldn’t be loosing any sleep . 

Ive usually replaced them...cos they are normally so rusted to death I ham-fistedly snap them off. I've likely used exhaust bolts as replacements too. Just been outside. Engine still in back of camper.

Set Screw - M8x1.25 / 30mm | 8.8 | ZFL

They are certainly not what I expected, not high tensile.  :?

I've also not go the plates. Can anyone find me a set of those please? My Google skills are weak tonight. lol

8.8 is high tensile, that's the correct spec

I know it's all about what you class as being "high tensile", but I thought 8.8 meant they weren't chocolate, but nothing special, 10.9 was where it became "high tensile".

I just had a google after your post, looks like I was wrong about that. 8.8 seem to be the lower end of the high tensile bolts.  :run

Replay was to maxstu...

That is very kind mate, but I'll find something local; one of my mates will have some suitable steel kicking about if I ask around.

I was just hoping to pick up the correct thing to save fabricating. I feel I've still got a long way to go to get the bus moving & making those up is wasted time.

Original ones were passivated, ie plated

and Zinc Flake Coating is what the automotive industry use nowadays instead of zinc chromate passivation, both are a form of zinc plating
