Which item forms its own matching thread in wood?

Explanation:
The key idea is a fastener that cuts its own thread in wood as it is driven in. A wood screw is designed with a sharp point and coarse, tapered threads that bite into the fibers and create a matching groove, so the screw threads into the wood without needing a pre-tapped hole or a nut. Panel pins have no threads at all, so they don’t form a thread as they’re hammered in. A cam bolt uses a machine-thread that usually works with a nut or insert and relies on those threaded parts rather than cutting into the wood itself. A jig is simply a guiding tool and has no threading involved.
