Self-Drilling Screws are commonly known by the brand name TEK® screws. Jake Sales offers self-drilling screws that have a pointed end that allow the screw to puncture thin materials. Generally, TEK® self-drilling screws are used for metal-to-metal or wood-to-metal connections and are most commonly used in thin metal applications.
About Tek Screws
Tek screws are screws that have a very small carving at the end of their tip, called a drill bit. The drill bit tip creates a small hole by tapping before driving it in. These screws are commonly used since they offer so many benefits, such as:
- Time-saving: Tek screws cut back on the number of steps necessary to complete projects.
- Pilot hole drilling not needed: The drill bit provides a starting point for the screw to drill into, making pre-drill not necessary.
- No corrosion: Tek screws are made from stainless steel and other materials that won’t corrode.
- Durability: You can count on your Tek® screws having a long life span, whether you use them in multiple projects or they’re left in extreme conditions.
- Consistent performance: You can expect the same high performance every time.
What Are the Tek Screw Sizes?
Tek screws come in multiple sizes, and depending on the type of work you are using them for, will decide which type you need to complete your project. Self-drilling screws are available in various diameters, lengths, and head styles. The diameter of a Tek screw is indicated as a numeric size with a range that runs from #0 to #15. The higher the number, the larger the diameter.
How Do You Use Tek Screws?
Drills or screwdrivers are often the tools of choice when using Tek screws. The biggest benefit of self-drilling Tek screws is that a pilot hole is not necessary when using them. If you do choose not to use a pilot hole, drive the Tek screw in slowly to ensure it goes in straight. Once it is in, tighten it firmly but without using excess force. Overtightening can cause head stripping, which makes it difficult to remove the Tek screw in the future.
Whether you use a pilot hole or not, you want to make sure that the metal thickness is thinner than the length of the drill point on your Tek screw. The screw will snap if its threads make contact with the metal’s surface before the tip has bored through, as this will result in the tip and the head of the screw moving at different speeds and generating stress in the middle.
