Uh huh... not true.
Ummm...yes true. It is really obvious when the dies get worn and a
flashing start to show up, like on a cheap plastic model.
Actual production of screws comes in gress what? Roll
of wire!
Snipped to short lengths by shear action then fed to 2 or 3 machines
then in the end is screws.
Well, yes, I assumed that everyone knew that. Screws have basically always
been made like this.
These "ultra-cheap" screws start out the same, with a head formed exactly
the same way, but then the blank is fed into a two part die that cuts the
thread by "smashing".
