Brake rotor fasteners?

[benhall]

Ive been overhauling the brakes on my FZR1000 and some of the rotor bolts were a pain and fucked themselves and some were already replaced with unmatched types.



Anyone recommend a nice place to get fasteners, would love something that doesn't go all pox like steel ones do, little dubious about using stainless

Is titanium the only other option?

they are button head M8X25 socket type

Go past any good fastener shop with a couple and chat to the guys there. High tensile, plated steel. Stainless will be okay (see www.probolt.com).

Or just go see your Yamaha shop. Those ones will have lasted 20 years okay.....

I came across this site the other day looking for something similar - http://www.tooltimeonline.co.nz/prod...ory/fasteners/

Blacks Fasteners.

I use Anzor a lot: http://www.anzor.co.nz/napier-branch

[benhall]

id like a full 18 of them and after spending over 300 dollars on brake rotor seals from Yamaha I'm a little reluctant on getting OEM stuff.

Fastener guys in Napier are less the helpful... guy from steel masters flat out refused to say they do socket screws when they have them on the website

I could get these

and more to the point what are your thoughts on stainless cause the anzor guys here are awesome

maaaaaaaaate. Steel masters up here are good. A damn shame yours arent.

Define whst you want
"socket screws" arent a thing.

Stainless is ok. I'd go the softer 304 which will be more tensile than the 316. I doubt either will shear, but that would be my pick.

Bit hard to tell in that picture, but are they fully threaded? Many disc bolts will have a flat along the bolt for the disc holes. SS is also weaker than high tensile steel. Wouldn't worry too much about that though, probolt sells 316 SS bolts for discs so it can't be too shit.

From memory Stainless and Aluminium are not as great a combination that you might suspect.
Ti also galls in its threads

I used to be wary of that too. But it's risk of galvanic corrosion is reduced when the aluminium part is large (ie, not the fastener) when there is no corrosive electrolyte present (ie saltwater) and when there is a film of thread lube/locker between the two (loctite); all such factors should apply on a motorcycle.

ZP is another option of course, they're not as common in high tensile though.

Agreed. But they still corrode where the two meet.
Not sure what the standard coating are on the rotor bolts but I suspect its cadmium.
The point I was trying to make is Stainless is not a wonder metal in regards to its corrosion protection.
Looking at the bolts and the bikes vintage I wonder why not to use stock fasteners AS LONG AS THEY MATCH THE STD TENSILE SPECS and design.

socket screws, cap screws, everyones got a fucking different name

ill drop by anzor again, he was very reluctant because braking components, same feeling for me..

There is a small shoulder on them its about 4mm (so around the disk width)

I have acquired lovely brembo serie oro discs so not wanting to put rubbish old bolts on them

Not sure if you read my original post at all? 2 are missing, 2 fucked themselves so i had to easy out them and the rest look like shit and are ready to die and not come out... theyre not going back in. The chances of getting stock fasteners in NZ for an 89 bike is literately zero and if they are available are probably like 10 dollars a piece hence my post here

10$/go for your life...
Easy money id say.


Grade 8, 304 ss i tells ya.
