It seems like a little freebie thing that a machine shop or fastener shop would give out, kind of like a calendar or something, that has its name and phone number on it. I am much more likely to use it, rather than opening up my tap and die set. The only fine thread bolt I have used on the Cobra, that I can recall, is the balancer bolt in the crank that I replaced, everything else is coarse. I know the windshield area has Whitworth, and the back of my Vernier has a chart that seems like it's for converting metric to Whitworth, but it looks like it's in German. Regardless, I can't figure it out.
