There was a stand opposite us at the Exeter show, what he didn't stock isn't worth having.

Hi Jonny

Are you asking for metric fine thread bolts. Just thought I'd ask since these are harder to get hold off.
If you require bolts and nuts stick with standard threads. I used Imperial (UNF) for 99% of my car.

Try

I used them for all my supplies and they usually deliver next day if you want it.

Craggle,

the reason I was looking at fine thread bolts, although harder to get hold of, was for fixing the pipes and cables to the chassis rails (dax de dion). With those fine threads I thought u could get more threads in the wall thickness giving a better fix.

All advice gratefully received - i'm just a novice at this!

Use UNF or BA threads then - both have a fine pitch. Suitable taps are available.

Alternatively, use a hardened threaded hex headed self tapping fastener either bright zinc plated or stainless steel. Dax supplied me with these when I carried out the jobs you describe.

Personally i'd rivnut it rather than tap it if the metals thinish.

You could try www.avonstainlessfasteners.co.uk got all my SS stuff from them, and they do mail order.

I drilled & tapped my std Dax chassis with M4 & M5 for the jobs your describing and didn't have any problems using std metric threads.

Margnor are also a good source for nuts and bolts and they accept any size order.

Hi Jonny

I did the same as you by drilling and tapping the chassis but used standard metric threads. M5 I think.
The chassis rails are thick enough for this and you wont be doing them up too tight anyway.
Rivnuts are great for certain jobs but they are expensive, Time consuming and ideally you need a special tool to do them up with.
Recently at work I had the opertunity to try to get a bolt out of a rivnut that was rusted in the thread. Once the rivnut starts spinning in the box section you will wish you had drilled and tapped it instead!.
