Tek or Self-Drilling Screws for Metal Sheets?

There is a lot of work involved in drilling screw holes in walls and other metal or non-metal surfaces. If the drilling is not done correctly, it might harm the wall’s surface as well as disfigure it. Consequently, drilling screws necessitates a level of precision and competence that few people possess. Fortunately, the emergence of Tek or self-drilling screws has made drilling a breeze, resulting in increased productivity and savings in time and money.

Self-drilling screws are sometimes referred to as ‘Tek screws’. Self-drilling screws and Tek screws are interchangeable. Since they produce a smoother surface and are more efficient, self-drilling screws are often preferred by industries that work with metal sheets. In the hardware industry, the self-drilling screw, sometimes known as a “Tek,” has been dubbed revolutionary because of its groundbreaking nature.

Fasteners with a drilling bit connected to one end, such as Tek screws or self-drilling screws, allow users to drill them straight into metal or wood without the need for a pre-drilled hole.

Self-drilling screws, sometimes known as Tek screws, are now widely utilized in industrial settings as well as in private residences. For metallic surfaces like thin metallic sheets, these screws are better since they are less expensive and more efficient.

The TEK number on the tip distinguishes these screws. Overall, this value refers to how long each screw’s drill point extends. The TEK 3 is the most widely used TEK Screw point. Metals as thin as 12-gauge steel can be drilled with them, and they can even penetrate metals as thick as 20- to 14-gauge. A TEK 5 point is recommended for use on 14 gauge and smaller.

A hard metal is used to make self-drilling screws, which are often heat treated to make them tougher than the material they are being drilled into. 410 Stainless Steel is the most commonly utilized metal in these screws. While regular 18-8 stainless provides corrosion and rust resistance, this grade has been heat-treated (up to 40 Rockwell C) so that the drill point can penetrate metal.

To understand why Tek screws or self-drilling screws have become so popular, we’ll take a look at the different benefits they offer and see how they stack up against the competition. 

What is the major difference between Tek & Self Drilling screws?

Screws that come with a pre-installed drilling bit are known as “self-drilling screws.” As previously stated, these screws do not necessitate pre-drilling a hole like standard screws. Tek is a well-known manufacturer of high-quality screws and fasteners around the world. As with the best brands, the product’s name has become synonymous with the company’s name. This means that a Tek screw is the same as a self-drilling screw.

Engineers and hardware professionals occasionally conflate Tek screws and self-tapping screws, which contributes to the confusion. In contrast to self-tapping screws, Tek screws are self-drilling screws, however the latter function on a different logic.

Here’s what we find:

·         If you are using self-tapping screws, you must drill a pilot hole before using them. There is an additional dent formed by taping the screw threads into the hole after the hole is made. For metal and hard wood, tapping screws are the preferred method of fastening. Tap screws don’t always have pointed tips; others have rounded ones. Some people are downright rude.

·         The Tek screw, also known as the self-drilling screw, eliminates the need for a pilot hole entirely. Drilling and fastening functions are combined in these screws. The screw’s drilling end automatically drills neat holes in surfaces. This type of screw is best suited for attaching to metal. For fastening thin metal sheets, experts recommend using these screws.


During the Industrial Revolution, screws and fasteners have been referred to as game-changers. Screws were first widely used in large industrial manufacturing in the late 18th century, despite the fact that the Greeks and Assyrians were well familiar with their usage. The usage of screws, particularly self-drilling ones, on metal sheets has grown in popularity around the world as thread form standardization and structural development have increased. Depending on their shape, self-drilling screw manufacturers provide a wide range of these screws.

Using self-drilling screws over conventional ones has several advantages, as demonstrated in this piece of writing. Self-drilling screws are a considerably superior option than regular screws in terms of efficiency, time consumption, and end product. Because they don’t necessitate any additional pre-drilling, these screws are clearly superior.

Self-drilling screws are commonly used to hold metals, such as steel, together, and are often used to join sheets of metal. The characteristic flute or point at the end of each screw identifies these screws. They are used to cut down on both time and effort because they don’t need to drill a pilot hole and tap it before screwing in an actual piece of metal.
