Self Tapping Screws, Finish : Zinc Plated

Self-tapping is the ability of a screw to advance when turned, while creating its own thread. This ability is sometimes created by a gap in the continuity of the thread on the screw. These edges cut a thread as the screw is driven into the material. The cutting edge drills away the material, leaving a hole for the screw to go into. Self-tapping screws are used in a variety of applications ranging from DIY to surgery. A dental implant is an example of a self-tapping screw used in surgery.
