There is no such thing as an AF thread. If it's oldish and american it's likely to be UNC. If your measuring of the diameter is accurate, I think you'll find it's 3/16"unc and a 3/16"whitworth will screw in to a 3/16"unc. A bit tight, but what else could you ask for, grease it, it'll keep out the water. At a push, an M5 could be made to work. A bit of studding and a few nuts and washers. Some 3/16" fencing wire with a thread on each end would do. It'll be galvanised too. Be inventive. Living at the end of the Ardnamuruchan road, I'd have thought you would have developed this skill a while back.

Length of stainless steel bar: used a die to cut a thread onto it, and welded a nut onto one end. OK, it's not the worlds most well-enginered bolt, but it does the job!

Quite a performance for something that a bolt making machine will stamp out in under two seconds!

What was that bolt for?

It was one of the five bolts that held the lower leg on: the original one got damaged. Having got a slightly newer one I attached it only to find the fifth fixing bolt (the one at the front) wouldn't fit. I couldn't find anything that would, so made this one to fit the gap (where the bolt fits in) perfectly.

Sure, but i like to keep things original on a machine so people in the future could play with it to and get stuff undone, The fence wire is not a bad idea.. haven't thought of that one yet! Thanks!

There is a slight difference between being inventive and being a bodger.. i like to keep stuff that it will work, and will last rather than "Och, it will do her fine for a few months... if it packs up, we'll see then!"

Only been living here 2+ years!

Thanks for your help anyway Turbo Diesel, i suspected that it would happen since i think that AMI also has a contract with Barrus.

Okay then, Going for the lazy way, i emailed one of the companies asking if they stock something similar, and Rogue Wave, can you please hand me that adress?

Mr-d, it looks as though you're back to the fence wire and the Whitworth die.

I've checked me thread tables for you. It seams that I've given you a bum steer because UNC threads appear to start at 1/4" so either yours is not UNC or you've measured it wrongly. They have a 60 thread form which is the same as metric threads.

Whit threads use a 55 thread form and they start at 1/8".

You don't tell us about your engine but could these bolts be M5? Thats a shade bigger than 3/16" and a quite a fine thread.

Getting suitable bolts will be dead easy once you identify the thread. See if the one you have left screws into any of your dies or screws into a nut which you know the size of.
