Self Drilling Screws Manufacturer
Self Drilling Screws Manufacturer
Self tapping screws and self drilling screws are the two primary forms of fasteners that are used in metal buildings or construction of Prefabricated Steel building. They also have numerous other applications, and their use isn’t limited to construction either.
Despite the different name, self-drilling screws are just another form of self tapping screws. Self tapping screws tap their own threads, but cannot drill through hard objects such as iron, copper or steel. They also require a pilot hole. On the other hand, self drilling screws don’t need a pilot hole, and like the self tapping screws, they can tap their own threads. Self drilling screw also have higher threads, compared to self tapping screws.
In a nutshell, all self drilling screws are a form of self tapping screws, but not all self tapping screws are self drilling screws.

These are just like other forms of screws, are available in a variety of specifications, which include:
- Overall built materials (steel, stainless steel, aluminium, brass or plastic)
- Head type (Philip, pozi, slot-hex, torx, square, etc),
- Thread type (coarse or fine)
- Thread count
- Chemical coating/plating (zinc, phosphate, copper, tin, etc)
- Diameter and length.
These are used for their accelerated installation time, which lowers the overall costs and the need of additional equipment. Their excellent fastening efficiency in steel makes them a popular choice for steel frame constructions, or fastening of other materials to steel frames. They can also be used for fastening objects to wood, and are widely utilized for structures such as wooden floors, wooden roof decks and wooden doors.

Frequently Asked Questions
Q.1 Do you need a pilot hole for a self-drilling screw?
A self-drilling screw features a drill point that mimics the point of a drill in look and function. The drill point enables the self-drilling screw to drill into hard surfaces, such as metal and steel, and tap its threads in a single operation. The need for a pilot hole is thus eliminated. Note that, self-drilling screws and self tapping screws are much the same, except for the drill point.
Q2. What are the best self-drilling screws?
ScrewExpert self-drilling screws are inarguably the best. We use top-grade materials, cutting-edge technology and compliance standards to manufacture screws that perform and last. Each screw is tested for safety, performance and overall quality to ensure complete peace of mind to you. The screws are available in regular and metric shapes and specifications to support all application requirements across industries. Plus, our prices are highly competitive.
Q3. How do you know if a screw is self-tapping?
A screw will be a self-tapping screw only if it can drill its hole when it’s screwed into a substrate. The self tapping screws feature a cut on the thread that breaks the thread continuity and gives rise to a flute and a cutting edge resembling those on taps. This gives it self-tapping capabilities for harder substrates. On the other hand, the self-tapping capabilities for softer substrates can be attributed to a tip that tapers into the Type AB Point.
Q4. What is the difference between self-tapping screws & normal screws?
A self-tapping screw is a specialized screw capable of cutting its thread when driven into a mating substrate. Regular screws, on the contrary, lack this ability and hence, require a pilot hole. The self tapping screws create a tiny hole into the substrate, resulting in a close friction fit, which wards off vibration loosening and allows easy part separation when required.
