Go to local fastner supply's take bolt, ask do you have one of these, guessing it's a m,14*1.25
Good idea, ive found a good-looking local place. Cheers
You might be able to clear that thread out if you can source a tap. Do you a friendly m/c shop?
Sadly not, not round here at least (not had chance to make a nuisance of myself yet!). Once I've got the bolt spec, I'll probably just order one from Amazon, given it will probably be a single-use item in my lifetime.
My main issue is I'm not sure how to determine thread pitch (will Google later) so I'll just goto the fastener place and ask them what they've sold me . Everything I've tapped before has been M5 / M6 size and threads are either "coarse" or "fine". But I suspect it's a bit more technical than that
The easiest way is to use a thread pitch gauge, but if you had one you'd have done that already. It's worth buying one for other jobs, as they're cheap. Mine was about £5.
Next is to measure the distance between each thread crest using a caliper - a cheap digital one will be plenty good enough and you might already have one. You'll be looking at a measurement of 1.25, 1.5 or maybe 1.75 mm.
If you have a decent steel rule you could use that, but it does require a good eye.
While you have the measuring kit out, check the diameter of the thread as well. This will enable you to acquire a correctly sized bolt.
