Evening all,

I've recently had the bells from my 330mm brake setup Hard Anodised to protect them from the elements.

Now, when I was removing the bells from the rotors the bolts had corroded slightly and this made it a bit of a PITA to remove them.

What I would like to know is if anyone knows where I can get some replacement bolts which are corrosion resistant.

I've been trawling the web for most of the day, and there doesn't seem to be anywhere who can definitely say if they are corrosion resistant or able to supply them in the correct size.

The size of bolt I require is -

M6 x 25 Cap Head and I would need 24 of them.

If anyone could point me in the right direction, or are able to/know someone who can supply me with what I need I would greatly appreciate it.

You will have a local fasteners place who will help you (eg Allthread in Preston, Sterling Nut&Bolt in Peterborough). Failing that, someone like Shop4fasteners will help you, buit iirc they're bags of 50 or 100. Could punt on a couple of kits to other people on here with 330 setups.

Your originals in your avatar will be chemically blacked ht. Your only other easily available option is zinc plated (Grade 10.9 or 12.9), i wouldn't really want to use stainless but i have known it before, Hispec supply kits with stainless cap heads iirc. Depends what torque you've been instructed to tighten to.

Socket Cap Clicky

I'll take a set off you!

The zinc plated ones should last a lot longer against corrosion, but at the end of the day they're high strength bolts exposed to the atmosphere at high temperatures - they'll start to rust eventually.

Custom-made polybushes available - need an odd size or fitment? - anything from batch work to one-off pieces.

Titanium if the wallet will bear it.
You could possibly use an A4-80 stainless steel rather than the normal A2-60/70 or A4-70 bolts you usually see, but Ash would have to confirm whether they're strong enough for you or not.

I've got some nice shiny anodised aluminium ones

Or you could just use a little anti-sieze paste

Nah, should be able to get them for nearly half that, try TiBolts.co.uk

Their prices are very good, cheers for the site.

I'll see how I get on with the Zinc plated ones first, then if my numbers come up I'll invest in the Titanium ones.
