Probably a bit of a can of worms here.
Would an 8.8 rated bolt on a mono shock unit be an MoT pass/fail?
This is more of an academic question than anything else, as I'm intending to buy a new (correct) bolt, but I'm just intreged... ____________________ '07 Honda CBF500 / '93 Vauxhall Astra (www.fb.com/2wdOffRoader) / '04 Vauxhall Movano

8,8 should be strong enough in terms of tensile strength. You're using a locknut so there are no worries regarding security.
Therefore it's all down to fit. Of there is no play and it's not fouling anything, I see no reason it shouldn't pass. If there is play, it should fail.
You could probably argue that there shouldn't be a threaded section inside the shock bushing too but the MOT tester can't see that. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

It is a CBF, and yes the original bolt head sits in a recess. I had to make a spacer out of the original bolt head (photo attached).
As I fitted a second hand shock I needed to test it, so couldn't just fit the bolt without a way of holding it firmly. ____________________ '07 Honda CBF500 / '93 Vauxhall Astra (www.fb.com/2wdOffRoader) / '04 Vauxhall Movano

My CBF is too low for me really, and I keep catching my feet on the road on roundabouts and tight corners. ____________________ '07 Honda CBF500 / '93 Vauxhall Astra (www.fb.com/2wdOffRoader) / '04 Vauxhall Movano

Doubtful that MOT would notice but what you've put in is a long way from being adequate IMO. It's already visibly bending in the photo.
You've removed a M12 fine thread shouldered cap screw for a hardware- store M12 coarse bolt. Just losing the shoulder and measuring down to the thread's minor diameter loses you 71% of cross-section. Now the bolt (screw, actually) that's fitted is probably 8.8 grade but socket cap heads are 10.9 or 12.9 - each 125% and 146% stronger respectively - that's if the new fastener even reaches 8.8 spec.
A 71% reduction in cross-section and possible 65% reduction in strength makes your replacement bolt as poor as 46% the capacity of the one you've replace.
Time to re-evaluate what you have there IMO. ____________________ a.k.a 'Geri'
