Screw part

Abstract

[Purpose of the Item]: This invention relates to the design of a "screw part," specifically a screw part for securing an object and preventing the screw from breaking. [Design Description]: The "screw part" design of this invention is shown in the attached drawing. The screw includes a head, a shank, and a conical end. Its distinguishing feature is a cutting section and a chip-removing section on the shank. The cutting section has several annular grooves on the shank, with cutting blocks at two corresponding ends of each annular groove for cutting fibers. The chip-removing section is located above the cutting section and consists of multiple rows of teeth that collect and guide the chips. The dotted line portion shown in the drawing represents the part not claimed in this design. The single-point chain line shown in the drawing defines the boundary between the claimed and unclaimed design portions. This single-point chain line is a virtual, imaginary line and represents the part not claimed in this design.
