Thanks for the comments guys!
Ed - the thread call out was an oversight, probably because I know Ken is going to match the nut to the screw.
Tom - I have absolutely no idea how to determine when a tolerance is required and what that tolerance should be. This is where I need help. As for the nut, which view is wrong (and why)? The thru hole is 3.5mm, as indicated but I wonder if you mean the hole that needs threading for the 1/8" oil nipple. Again, this is a lack of knowledge on my part in measuring a tapered hole. I had meant to discuss this with Ken but I forgot.
Ken - I too found that dimension strange and I checked it several times. I took the measurements at the end of the thread closest to the ø20 section, as this would have the least amount of wear. I'll check it again. I would have no problem with it being ø1.250. I simply wrote down the measurements that I got.
