Screwfix's HT BZP bolts and setscrews seem to be 8.8 but the Stainless ones are only 4.sumat as I found out when I bought some M10 x 25 for the caliper mounts. Still, they might come in handy somewhere in the build thats not too critical.

so where can I get stronger ones like 12.9's?

Think you'll need to ring a nut and bolt specialist, I use FR Scott in Hull
( 01482 324731 ), but don't know if they will post out, but they will sell individual pieces, not boxes of 100. Or you could try trawling around ebay, Dave.

They aren't really required, apparently the 8off 8.8 bolts that hold the roll bar on will be stronger than where the plate is welded to the chassis

Its always nice to slightly over engineer safety features if you wish though

Any type you want www.namrick.co.uk.

nice one tsm, that's a good link

I've welded in 8mm nuts as the book says. I hope thats ok for IVA or I'm screwed

Stainless is brittle and I would not use stainless bolts in a safety role, standard bolts are stamped 8.8 end higher spec allen/cap screws could be used.

I have used plated domed cap screws in the top plates in 10 mm,over engineerd for that bit extra as Mark say's.

You,ll be ok Gaz , as Mark says, those 8 bolts holding the roll hoop to the chassis will be as strong if not stronger that the welds around the suspension boxes ,
When I was fitting my rear back stays there was a discussion about how many bolts should be used to secure them to the chassis....some said 1, some said 2.....I,ve used 4 on each side so in effect I have 16 8.8 strength bolts holding my roll bar/back stays to the chassis....should be enough
