looks good - a couple of comments.
on the norris (see the photo posted earlier) there are a couple of v cuts n the square knurling so instead of just lines is a pattern or regular rectangles - looks great and is easy to do.

the top of the screw should be rounded over not flat (will work better)

and I am surprised you are using so fine a thread.

if you end up offering scrws for sale I probably won't as I have plenty on my plate now.
