Main features of wood screws

Wood screws have a bare rod at one end. The angle and pitch of the threads of wood screws and self-tapping screws are different.
Self-tapping screws have high hardness, wide thread pitch, deep threads, and a rough surface. Wood screws are the opposite. Another difference is more obvious. There is no thread at the back of the wood screw. Self-tapping screws generally need to be heat treated, but wood screws do not need to be. The concept of self-tapping screws is actually very general, because they are divided into many types according to different head shapes.
Uses of wood screws: Similar to machine screws, but the threads on the screw are special wood screw threads that can be screwed directly into wooden components (or parts).
