Nuts and bolts

In the process of belts, seals, etc.

Want to replace corroded nuts and bolts here and there to tidy things up as I go, but is there any spec??? Most of the ones I want to replace are for brackets and fittings.

Can I just replace with stainless?

as long as they meet or exceed 8.8 specs, there are a few 12.1 around as well

But is it ok to go for A2 stainless instead?

I used A2 stainless bolts for the water pump to prevent corrosion issues down the line so personally I think it's a good idea. For the tensioner studs etc I'd stick to OE fasteners though.

I was thinking of using them more for the various brackets and other not important stuff just to tidy up a bit. Plan to keep anything remotely important OE.

Think I'm going for the A2.

A4 is better, in very exposed area

just remember A2 is pretty soft, don't get over excited tightening them up
