Bolt size needed please

[Marks adventure]

I have removed my flappy valve and managed to snap both bolts off the exhaust clamps. i have since removed the broken bolts (with a little heat)

i now need to replace the bolts, any idea what size and thread i need to order please?

i have got the clamps and the little round things, just need the bolts that screw into the round things..

If you measure the broken bolt end section to the tip of the threads and round it up to the nearest mm that will tell you the diameter, the length you will know, it's standard not fine metric,
I vaguely recall 10 x 50mm to avoid a lot of exposed thread,
Double check as it was a while ago,,

The clamps are usually M8 standard. Avoid using stainless nuts on stainless bolts. The threads will self weld. Normal zinc plated nuts work well but can quickly get rusty. Brass look better but prone to shake loose.
