How do these differ from Kerks Rolled Screws ? Is Nook's intention is to
run Ball nuts on them ? ( thats what I'm thinking by looks of their web
site)

I know Kerks standard is .0006", but offer .0001". Of course those
screws are for Composite nuts.

My interest would be for non-ball nut style applications. We'll see how
the "1/3" less compares in the end.

thanks for the heads up,
