The Supertite thread forming Pozi Countersunk Head Screws form a thread as they are inserted. They displace the material around the pilot hole so that it flows around the screw thread as it penetrates. Due to no material being removed, the mating part creates a fit with zero clearance. They are generally used when large stresses are needed to increase resistance to loosening.
The Pozi Countersunk Head Screws sit flush with the material surface.
