Good points by Ken and Ted, I wasn't worried about thread pitch as the engine mounting bolts are all going onto their own nuts but I hadn't considered this with the lower yoke pinch bolts. Are they standard 1.5mm pitch on the m10 bolts?I might have to have a rethink on the lower engine mounts.

IIRC Kay fast and middletons don’t have t some of the bolts in the correct pitch and I ended up getting them from china on ebay( bottom yoke maybe) what I have found is that by grinding off the lettering , polishing up with the brush wheels and bench polisher the heads can quite easily end up with a mirror finish. https://www.ebay.co.uk/itm/354792939265?var=624112326971
Oh b@gg@r, I ordered from Middletons but thought the 14mm headed M10 bolts were metric fine so ordered some nuts on Ebay, turns out they are 1.25mm thread pitch.

If you were not sure of a thread size you screwed your bolt in by hand to find the right siize. You could also check nut sizes by sizing a bolt then trying your nut on an identified bolt.It was a promotional tool at the garage where I worked - it came free with some red tins of fastners by a manufacturer - forget the brand name now something like Tewul ?
