The Washer head screws self-tapping screw with a cut tail refers to thread cutting screws that do not need to be used with a nut and a washer. The thread is self-tapping, and the tail is tapered. When the triangular tooth is screwed into the hole in the plastic metal material, it will form an internal thread in the hole by extrusion and form a reliable locking threaded connection.Self tapping screws include thread cutting screws and thread forming screws.

Self-tapping screw means: they can drill a hole that does not need to be tapped. The screw used is different from the general one. The head is pointed and the pitch of the thread is relatively large. It is a bit like a chipless tap and can be screwed in without tapping, metals and plastics usually use this method.
It can “tap-drill, extrude, press” the corresponding thread on the material to be consolidated, relying on its own thread so that it can be closely matched with each other.
