I'm pretty sure at least the BF inserts are cold cast and then tapped. I remember reading that they leave the flecks of flashing on the outer threads to grab the ski core better. Could be a cast allthread, though. I don't know. There's an image of the surface roughness somewhere.
Edit: yeah, rolled maybe. Inner threads tapped

Whoever said that was probably trying to "explain" burrs or marks resulting from a dull cutting tool, machine vibration, etc. Turn sloppy machine work (that doesn't hurt anything, so who cares) into an "intentional feature".
Yeah, no what really happened is I read something a long time ago and can't fucking remember what I read now. I'll post it if I find it, although your response above could likely be inserted above or below once I do. My point was more about how McMaster/Carr inserts != (BF//QC) inserts.
Edit:
Stainless steel inserts chemically passivated for epoxy retention
