Effective date : A self-drilling screw includes a head and a shank having a drilling point defined at the distal end thereof; said drilling point further includes a first drilling section adjoining the threaded portion and a second drilling section adjoining the first drilling section.

Two cut grooves are defined on the second drilling section and communicating with the first drilling section. Due to the two drilling sections, the making drill point dies are less damaged when shaping merely one section of drilling point.

Besides, the smooth surface of the first drilling section provides space to put a trademark. Field of the Invention. The present invention relates to a self-drilling screw, particularly to cause minor damage on the making drill point die when shaping the drilling point.

Generally, the length of the drilling point of a self-drilling screw is designed according to the thickness of the object that a self-drilling screw is going to penetrate. An example of long drilling point of self-drilling screw is described below. Referring to FIG.

Said shank 12 has a threaded portion and a drilling point The drilling point , defined closing to the shank point, includes a cylindrical portion and a cone-shaped portion tapering to the shank point.

Two cut grooves are defined on said drilling point to form a cutting edge on the boundary of the cut grooves and the outer periphery of the cylindrical portion and the boundary of the cut grooves and outer periphery of the cone-shaped portion In use, the conventional self-drilling screw has several defects.

The present invention intends to provide an improved self-drilling screw with a drilling point which can efficiently drill into the object and reduce the damage of the making drill point dies when shaping its drilling point. The present invention relates to a self-drilling screw that comprises a head and a shank, having threaded portion adjoining the head and a drilling point without threads, adjoining the threaded portion.

Said drilling point further includes the first drilling section closing to the threaded section and the second drilling section closing to the shank point. A cone-shaped portion is defined at the distal end of the first drilling section, tapering to the shank point.

The present invention will obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention. Said threaded portion is adjoining the head 21 and said drilling point further having a first drilling section adjoining the threaded portion and a second drilling section adjoining the first drilling section The second drilling section , including a cylindrical portion and a cone-shaped portion tapering to the shank point, has two cut grooves defined thereon communicating with the first drilling section A plurality of cutting edges is formed on the boundary of the outer periphery of the cone-shaped portion and cut grooves and boundary of the outer periphery of the cylindrical portion and cut grooves Said first drilling section has a smooth outside surface which is an area sufficient to put a trademark.

Besides, the outside diameter of the first drilling section is smaller than the outside diameter of the second drilling section.

As shown in the FIG. The debris of fibers is carried through the cut grooves to the first drilling section. The first drilling section is a slightly sinking section providing space to eject out the debris of fibers. As indicated above, the invention has the following advantages:. While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.

A self-drilling screw comprising: A head and a shank extending therefrom, said shank includes a threaded portion adjoining the head and a drilling point closing to the shank point. Said drilling point further has a first drilling section without threads, adjoining the threaded portion and a second drilling section, adjoining the first drilling section. Said second drilling section includes a cone-shaped portion defined at the distal end thereof and a cylindrical portion. Two cut grooves are defined on the second drilling section and communicated with the first drilling section.

A cutting edge is formed on the boundary of the cut grooves and the outer periphery of the cylindrical portion and the boundary of the cut grooves and the outer periphery of the cone-shaped portion. The self-drilling screw as claimed in claim 1 , wherein the outside diameter of the first drilling section is smaller than the outside diameter of the second drilling section. The self-drilling screw as claimed in claim 1 , wherein the surface of the first drilling section has a mark.

Robert W. Think of buttons and toggles updated to innovative snaps, hooks, and interlocking industrial parts. Mechanical fasteners have been around as long as mankind, but manufacturers of late have been re-discovering their quick, efficient and fail proof advantages when using them as interlocking individual components as compared with such traditional means of joining materials like welding, soldering, gluing and using nuts bolts, rivets and other similar devices. For many years, it has been virtually impossible to find a single-source reference that provides an overview of the various categories of fastening systems and their various applications. Design engineers should find this book to be an invaluable source of detailed, illustrated information on how such fasteners work, and how they can save time and money. Students, too, will find this book to be extremely useful for courses in mechanical design, machine design, product development and other related areas where fastening and joining subjects are taught.
