Screws are a cylindrical threaded device that has spirally threaded rings on the exterior surface that helps in converting the torsion tension to compressive force. This design is the primary reason for making use of the self tapping screws in bone surgeries. The thread design of the screw increases the holding force of the bone joint. It enhances the area tremendously and helps in distributing the stress of the screw point and the bone sections. Self- tapping standart screw are usually used for attaching the bone implants, fixing of two broken or improper bones, for tender tissue fixing and holding of the tissues.
