Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If angles/shapes/sections
Hex profiles approaching structural shapes may classify differently.
If machined to gears
Post-cold-forming gear tooth cutting makes transmission gearing.
If free-cutting steel composition
S/P additions for machinability create free-cutting steel subheading.
