Up until now, raw material seemed to imply a circular or rectangular cross section, with at least one dimension constraned to less than 1/8" or 1/16".

If the dimension restriction goes away, then we're left with any solid material with a circular or rectanglar cross section.

Of course lead-screw violates this, but I suppose it's an extension of the "Fastner" caveat,

but then.... what about angle, and tubular stock...

It does seem like it's going to be hard to know for sure what is a raw material.....
