There are literally hundreds of different types of screws available, ranging in size, shape, material, and design. One of these types is the self-tapping screw, which live up to its namesake by tapping into its own hole as it is driven into the lumber or material. They are commonly used in the manufacturing and construction industry, as they save time by eliminating a step from the process. To learn more about self-tapping screws and how they work, keep reading.
Self-tapping screws work by cutting into the thread of the screw; thus, creating a flute and cutting edge, much like a tap. This is in stark contrast to traditional machine screws, which typically require a pilot hole to be driven through. And with one step out of the way, it promotes greater efficiency and productivity. The mechanism behind self-tapping screws varies depending on the material that it is being driven into.
For softer materials, such as wood or soft plastic, the screw may feature a tapering tip that forms of a gimlet point. This tip then displaced the material as it is being driven, creating a pilot hole as it works through the material. Keep in mind, however, that the hardness and depth of the substrate must be within reasonable limits; otherwise, the self-tapping screw may fail to penetrate all the way through. This makes them particularly useful in applications involved hard substrates, such as assembly lines, carpentry and construction roofing.
If the material is rough, for instance, it may prove helpful to drill a pilot hole beforehand. Doing so ensures the screw will be positioned in the desired area, and that it will enter into the material smooth and without restriction. So when drilling the pilot hole, err on the side of caution by making it smaller than the necessary width. The information contained in this website is for general information purposes only.

One of the most important commercial fasteners in use today is the Self-Tapping Screw. Still in use today, there are now many types and styles of Self-Tapping Screws made to perform specific fastening jobs. However it is also often called a Sheet Metal Screw because they are primarily used in sheet metal. The drill point looks a lot like the point of a drill. It will drill a hole and form the mating threads in one operation.

When looking for fastening solutions, one common solution to use for routinely maintained products is self-tapping screws. What is a self tapping screw? Self-tapping screws are fasteners that are designed to drill their own hole as they are screwed into wood, plastic or metal. By using a screw driver and self-tapping screws, precisely fitted threads are created. Self-tapping screws are ideal for items that require regular maintenance and work well when working with two different kinds of material being fastened together. These screws either come with a blunt, flat, sharp or piercing tip.

A self-tapping screw is a screw that can tap its own hole as it is driven into the material. Self-tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design. Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate , often case-hardened. For hard substrates such as metal or hard plastics, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap. Thus, whereas a regular machine screw cannot tap its own hole in a metal substrate, a self-tapping one can within reasonable limits of substrate hardness and depth. For softer substrates such as wood or soft plastics, the self-tapping ability can come simply from a tip that tapers to a gimlet point in which no flute is needed. Not all self-tapping screws have a sharp tip. The type B tip is blunt and intended for use with a pilot hole , often in sheet materials.
People often confuse self-drilling screws for self-tapping screws. In terms of likeness, self-tapping screws and self-drilling screws can tap their own threads, but generally, self-drilling screws come with a higher thread count compared to self-tapping screws. In a nutshell, all self-drilling screws are a form of self-tapping screws, but not all self-tapping screws are self-drilling screws, and due to the above differences these screws cannot be used interchangeably, and mixing them may cause some headache at the very least. Self-drilling screws offer faster installation time.

Self-tapping and self-drilling screws are two types of screws used in metal building and general construction, as well as many other applications and industries. Contrary to popular belief, the two terms are not interchangeable. Often, our customers ask for self-tapping screws when they actually want self-drilling screws, or vice versa. As the name suggests, self-tapping screws are screws that have the ability to tap threads into the material.
What is the Difference Between a Self-Drilling Screw and a Self-Tapping Screw?
The present invention relates to threaded fasteners and more particularly to a self-tapping screw and a method and apparatus for making same. A wide variety of self-tapping screw forms are presently available. Self-tapping screws may be of the thread forming type, thread cutting type or the metallic drive type. The thread forming type self-tapping screws typically include a continuous thread and a tapered point.
CARL H. Robertson Mfg. This invention relates to screws of the type which are adapted to be threaded into untapped holes, and the object of the invention is to provide a screw which can be driven into untapped holes with greater facility and less driving torque than previous screws of this type. Another important object is to provide a screw as aforesaid which can be driven with a minimum requirement of driving torque into a blind hole provided for example, in structural and lower carbon content steel members, zinc or aluminum die castings, or brass or bronze forgings or the like, and which will swage form a thread formation on the wall of the untapped holewithout chipping of the wall surface so that the screw can be run clear to the bottom of the hole. Still another and important object is to provide a screw as aforesaid which will be self-locking against removal unless deliberately removed with a driver.
