The History of Self-Drilling Screws

Tek is to self-drilling screws as Kleenex is to nose tissue –  a brand name. As the first of its kind, “tek” became synonymous with the self-drilling screw design, and now tek screws are essential for a range of applications today.

At All Points Fasteners, we know what professionals look for in self-drilling screws. It’s helpful to learn more about this essential fastener and how our team can help you find the right tek screw for your project.

How Do Self-Drilling Screws Work?

The original self-drilling screw featured threading like a regular screw, but the end had a drill bit shape. This drill bit end eliminated the need to pre-drill a hole before using a screw, saving time and money. After the drill bit punctured the surface, the sharp threads tapped the material to create a strong seal with the screw.

The original design also included a tall head with serrations under the washer to add additional locking abilities. This detail ensured self-drilling screws stayed closely fastened to their materials, making them reliable for many applications.

As this time-saving screw design became more popular, other companies found ways to produce a similar product with low-cost materials and fewer features. Many modern self-drilling screws have eliminated the serrations but maintained the signature drill bit end.

What Are Self-Drilling Screws Used for?

Self-drilling screws are useful for fastening wood and metal. They can attach wood to wood, metal to metal and metal to wood, and they’re ideal for most lightweight and low-density materials. It’s also easy to know how to use a self-drilling screw due to their simple design. Applications for these screws include:


  • HVAC projects
  • Metal roofing
  • Cladding
  • Steel framing

Tek screws are also helpful for many types of metal building and light-gauge metal assemblies, making them common in most general construction environments. With a range of head types, lengths and shank sizes, these screws adapt to your project with ease.
