Teks self tapping screws include a drill tip with a little carving piece that makes them self-tapping and self-drilling, eliminating the need for pre-drilling. For metal-to-metal applications, they are frequently utilized as HVAC ducting, solar panels, electrical, and metal roofing screws. The requirements for the value of screws have altered thanks to Tek screws. They appear so commonplace yet are pretty helpful on the job site.
When Do You Use Them?
Sometimes you can’t make a hole because the material is thin, such as sheet metal, or because you can’t get to the back to put in a nut. But you might want to take the device apart in the future, so blind rivets won’t work. In this case, good quality Teks self tapping screws are the best choice.
Self-tapping screws are fasteners with threads on the outside. They can “tap” their threads into metal and non-metal materials. Some screws need a hole, and the size of that hole is often important. Other screws can drill their holes. Each type has a name that describes how their threads and points are made. The threads will either be like those on wood screws or like those on machine screws. There are different kinds of points, such as “standard,” “sharp,” “blunt,” and “drill.”
What the Numbers Mean
The drill bit tips on self-drilling screws are numbered from #1 to #5, which shows how long the flute is. The thickness of the metal the Tek screw can drill into is determined by the flute. That means that the thicker the metal it can go through without a pilot hole, the higher the number. For example, Tek 5 self tapping screws can go through metal up to 0.5 inches thick.
