I'm replicating a drawer handle that fits on an M4 screw. If you'd look inside the plastic hole, you can see a gold-colored metal tube that has screw threads. That's what the screw screws into.

My question is: What is the technical term for this metal tube? I want to order some of those.

    Those are machine threads not screw. – Mazura Oct 18 at 18:06

That is simply called a threaded insert. It is either first placed into the mold, then plastic injected, or pressed in after the plastic handle is injected. Google images for "threaded inserts for molding".

McMaster Carr or Fastenal if you want to buy some.

Since it's mounted to something I'd probably go with (female) threaded stud or insert.
