Tek screws have changed the standards for the value of screws. They look so ordinary, yet they are so handy to have on the job site. All Points Fasteners has a variety of Tek screws on hand for you to get for your next job.
Tek screws — also called self-tapping fasteners or self-drilling 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 very popular since they offer so many benefits, such as:
Tek screws are meant for metal to metal applications only, except for the ReamerTek screw, which is designed exclusively for applications that are wood to metal.
Self-drilling Tek screws can be used for any job that would benefit from the screw’s many capabilities. Contractors use Tek screws for screwing metal to metal and sometimes wood to metal. They are common in the electrical industry, and they can be used for work with steel studs and other thin metal applications.
Depending on the thickness of the material you are drilling into, you have several drill points available. They range from 1 to 5, the shortest being a Tek 1 and the longest being a Tek 5, sometimes referred to as a “beam buster.” Tek screws allow the user to fasten two pieces of material together without pre-drilling.
Standard self-drilling screws were never designed to go from metal to wood. The diameter of the hole that the drill bit creates is nearly the same diameter as the outside threads of the threaded portion of the fastener. If that’s the case, this will not allow the threads to tap into the wood and be secure. Tek screws are also ineffective for wood to wood applications.
The exception to this is some self-drilling screws that are manufactured for roofing applications. The drill bit on those screws is very tiny — a #1 drill bit — and the diameter of the hole that the drill bit makes is substantially smaller than the diameter of the outside threads of the rest of the screw. This allows the threads to bite into the material and the screws to self-tap into the metal or wood for a secure hold.
Tek self-tapping screws come in varying sizes. Self-drilling screws are available in a variety of shank diameters and lengths, as well as head styles. The type of work you are using them for will dictate which type you need to complete your project.
Two of the most common types of head styles on Tek screws that you will find on the market are:
Other than that, all other styles of heads on self-drilling screws generally have a Phillips drive, which helps in driving the screw in straight. The square drive is becoming more and more desired, as the bit is less likely to slip while driving. Another common type of screw is the flathead screw, which is used when you need a flush surface. Reamer Tek screws — self-drilling screws with wings — are the ultimate wood to metal screws.
We are often asked for stainless steel self-drilling screws. They are available, but the tips are not the best for drilling into stainless steel. For stainless steel applications, we suggest bi-metal Tek screws, where the body of the screw is stainless steel, and the tip is made of carbon steel, which allows the screw to drill into the stainless steel with ease.
