a2 stainless vs 8.8 steel, brake calliper fasteners

well i purchased some a2 stainless steel fasteners last night for my brake calipers but since then thought about it a bit more and it turns out that a2 does not have as much tensile strength as the 8.8 steel bolts, the problem is i just cant find any m10 x 35 1.25 pitch zink plated 8.8 bolts (socket cap or flanged nex preferd)

my question is will the a2 stainless ones be ok? or should i at least get a4 stainless bolts ?

(pro bolt dont state what stainless they use, only the grade titanium they use on there titanium bolts (grade 5))

I doubt Pro Bolt aren't going to sell bolts that ain't up to the job, otherwise they'd not sell any

Ring them up an specify they're for calipers

I aint had any issues with my Pro Bolt caliper bolts.

^ will do, the bolts im looking for are under calliper mount bolts for the rsv mille 98-02 so they are defiantly for callipers it just dose not state what grade

Edit: its 316 grade so A4, looks like i need to get some as the one i got were a2

A2 M10 are gonna be way stronger than you need imo, suzuki make theirs of cheese and they seem to do an ok job.

Well if you want steel flanged bolts m10*1.25*35 with a coating a search found these. Cannot say anything about them, simply a google result

it doesn't say what they are made of, thanks though just says chrome

I personally would not use stainless bolts to mount my calipers. I use zinc coated hardened steel. My bolts are now a bit furry - but better than than one shearing. Go for titanium if you want them to look good, stainless should not be used in safety critical applications.

Chrome coating a bolt will reduce the properties of the original steel, which is why chromed caliper bolts are usually a larger size than you really need. Still better off going with a coated bolt rather than stainless though.
