Be Successful In Sourcing Self Drilling Screws
One of the most important commercial fasteners in use today is the Self-Tapping Screw. Among the earliest “engineered” fasteners, Self-Tapping Screws were made from hardened steel and its use was instrumental to the Industrial Revolution. Still in use today, there are now many types and styles of Self-Tapping Screws made to perform specific fastening jobs.

Unlike Military or Aerospace Fasteners, terminology used in the Commercial Fastener Trade is often imprecise and can sometimes cause confusion; one example is the distinction between Self-Tapping and Self-Drilling Screws..
Self drilling screws have point to cut through material and eleiminate the need to drill a pilot hole. Truss head screws are weaker than pan or round heads but preferred in applications where minimal clearance exists above the head. Modified truss heads offer low clearance and an extra large bearing surface.

The ability of a screw to advance when turned, while creating its own thread versus, say, machine screws which require a pre-threaded nut or other female insert. Self-Tapping screws can cut their own threads as the screw is driven in to the material. They function by having a cutting edge which drills away the material, making a tiny hole for the screw to go into.
A self tapping screw can also be self drilling. Basically a self drilling screw is a tapping screw that doesn’t need a pilot hole. They both technically tap their own threads, all screws do this to varying degrees. But, the self drilling screws skip a step in the process.

Screws are driven into steel were driven with three (3) exposed threads on the off-side of the connection, then pulled out with the testing machine. Wood: Screws were driven 3/4" into the wood material then pulled out with the testing machine. Note that all results were obtained in strict adherence to ASTM test protocols.

Self-tapping screws are used for all sorts of material including wood, metal, and brick. These screws cannot drill through metal and require a pilot hole to be pre-drilled before installation. A pilot hole is created by using a drill bit which is slightly smaller than the screw and the threads of the screw tap the metal or wood while the screw is being installed.
There are many different types of points that a self-tapping screw can have that assist in the tapping of threads into various substrates.These screws can be identified by the drill bit shaped point of the screw and are designed for a variety of applications such as fastening metal to metal and metal to wood.14

Successful construction projects are often driven by budget and time constraints. Self-drilling screws can help on both fronts. When you use self-drilling metal screws, you avoid the need for separate drilling and tapping, and you get the durable, long-term performance of stainless steel construction. Many construction projects call for the fastening of steel to steel, and self-drilling screws for stainless steel are ideal for getting the job done quickly and getting it done right.
In short, when you have specific needs in self-drilling screws, we have the options that allow you to find and secure exactly what you’re looking for. Quality construction projects begin with quality materials.

Two thread-forming self-tapping screws with different heads A self-tapping screw is a screw that can tap its own hole as it is driven into the material. Self-tapping screw with flute and type B (blunt) tip Self-tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design.
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).
Like the tip of a nail or gimlet, such a point forms the hole by displacement of the surrounding material rather than any chip-forming drilling/cutting/evacuating action. 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.
Self-tapping screws can be divided into two classes; those that displace material (especially plastic and thin metal sheets) without removing it are termed thread-forming self-tapping screws; self-tappers with sharp cutting surfaces that remove the material as they are inserted are termed self-cutting. Thread-forming screws may have a non-circular plan view, such as the five-fold symmetry of the pentalobular or three-fold symmetry for Taptite screws.
Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a center drill. These screws combine a thrilling-like action and the fastener installation itself into only one driving motion (instead of separate drilling, tapping, and installing motions); they are thus very efficient in a variety of hard-substrate applications, from assembly lines to roofing.
Pan-head PK Self-tapping screws are common in electrical equipment, while flatter-headed truss or flat countersunk headed self-tapping screws are more common in aviation applications. Winged self-drilling have thin wings wider than the thread formed just behind the self drilling head. These cut a clearance hole in soft materials (such as wood or plastic), but are destroyed by more robust materials (such as metal).

Self-tapping screws are used in a variety of applications ranging from DIY carpentry to surgery. Dental implants and orthopedic bone screws are both examples of self-tapping screws used in surgery. Different thread profiles are used for either denser cortical bone or the spongy cancellous bone. "Fastenerdata". Retrieved 10 November 2017.

Self-drilling screws eliminate the need for a pilot hole, but can tap as well. Self-tapping screws tap their own threads, but cannot drill through metal and require a pilot hole. These screws are not interchangeable, and mixing up the two can cause many headaches or possible failures in the field..16
When selecting a self-drilling screw, consider the material thicknesses and types of materials to be joined. Following are some key design features to look for when selecting suitable fasteners. allow drilled material to exit the hole. Completely embedded flutes can no longer remove these chips, which contain approximately 80% of the heat created by the drilling process.
The unthreaded portion of the point, (pilot section) must be able to completely drill through the material before the threads engage. If the threads engage before drilling is complete, the fastener can bind and break. are used on some screws that fasten thicker materials, such as wood, to metal.
