Facts and Facets to Learn about Self-Tapping Screws

by Super Screws Best Nut Bolt Manufacturer Company in India

A self-tapping fastener is a type of screw with the ability to tap its hole when driven into the metal. In short, self-tapping screws describe the most archetypal form of thread-cutting fasteners that can produce a thread relatively in sheet materials or soft material (except for wood screws). There are various forms of self-tapping screws that include self-drilling, thread rolling, and more.

But how do self-tapping screws get used?

As described above, the image of these essential tools is just one form of archetypal screw image. These screws are thought to be the countersunk screw that comes with a sharpened point and a drive. But if you perform an online survey, you can find innumerable examples of it. Despite its prominent popularity, the question still remains the same: how will you use these self-tapping screws? To learn about the procedure, let’s first get an insight into the difference between self-drilling and self-tapping screws.

Learning the Difference between Self-Drilling and Self-Tapping Screws

Tapping is the act of building a thread. In fact, tapping isn’t an act of creating holes. If you take the example of soft materials like wood and plastic, some are overlapping in those procedures because of the fact that a self-tapping tip is sufficient to make a hole (as required).

Nonetheless, with some hardwoods and metals, the pilot hole can be drilled prior to tapping the thread. This lets this post narrate about the choice for the right self-tapping screw. Given that the market brings several self tapping screw manufacturers under the limelight, how will one choose the right type of drive? To begin with, the following narration will give an answer.

Selecting the Right Drive Type

A predominant consideration in self-tapping applications is to choose an ideal type of drive for a given work. As a matter of fact, the common choices are specifically invented for the self -tapping applications. The deeper socket drives also are used in high-torque applications regularly.

While installing the self-tapping screw, it must get aligned properly to make sure it’s driven into target housing at correct angles. It’s important when the screw is purposed to cut the hole, as one would not be able to identify any pilot hole for guiding the fastener. There are multiple methods that ensure perpendicular holes, from high-precision tooling to improvised jigs.

A hundred factors are required for the selection of the pilot hole. This includes preference in the amount of thread required. Fastener material, the given hole depth, housing material, and temperature, are some other considering factors. It’s close to impossible to guarantee the pilot hole size concerning specific applications. A pilot hole must be between the screw’s major diameter and minor diameter. However, it must vary in accordance with other external factors.


Thus, this compiles this post that narrated the facts and facets concerning self-tapping screws. One who needs to purchase these screws can visit the online website of every prominent fastener supplier in Delhi NCR to compare and select a comprehensive quote.
