Exclamation Aluminium bolts as strong as steel?

Want to replace the unsightly silver zinc plated bolts that came with my Top Secret diffuser and Autoselect canards.

Looking at 'Pro-bolt.co.uk', so will the aluminum bolts cope with high speed forces?

They are not as strong but for non structural use in the sizes you will be looking at for diffusers and canards they will be fine. Personally not sure they are worth the extra costs over steel bolts

Depends...

A shiny 7075T6 ally bolt will be half the strength of the same sized Grade 8.8 steel bolt. Titanium is a better match for 8.8 steel and is half the weight and wont rust.

Titanium is better but it will cost you more, you will be better off with a stainless bolt.

In the bike world there was a rule of thumb for lightweight bolts.

Load-bearing bolts need titanium and non-load bearing can be aluminium.

Of just buy stainless as others have said.

Reason: nothing other than not liking the shiny finish of the s/s bolt on carbon fibre canards and diffuser, it was last pointed out to me when l put pics up that it looked shit to put it bluntly.. Lol

If you use aluminium on a diffuser, being a very exposed area to crud they'll probably corrode in the threads & when you try to remove after a few years of road use you risk rounding off the hex heads. Stainless is OK. I've used a lot of titanium from them, but on bikes. Good quality stuff.

Might as well use stainless steel rivnuts and put anti-seize paste on the threads. Proper job then.
