In the construction and production of self-drilling screws, as well as their use, there are certain factors that need to be considered. The proper selection of a self-drilling screw can go a long way for ensuring a secure connection and rapid completion of the work.

As with any tool, proper performance can be successfully achieved by paying attention to the requirements of the tool. In the case of self-drilling screws, they can be constricted by the material used to produce them as well as the speed at which they are applied, each of which can fail mid-application if used inappropriately.

Drill Point Material

The point, which is connected to the flute of a self-drilling screw, is normally made from carbon steel that is less stable at high temperatures unlike high speed steel used to produce drill bits. Screws should be applied using some form of drill motor for protection against wear

In some cases, coatings can be applied, which offer greater strength and protection against rust and corrosion. A zinc coating on steel protects steel against corrosion.

The temperature stability of the drill point is proportional to the motor RPM, applied force, and the hardness of the workpiece. As each of these increases so does the heat related to the operation of the drill. A reduction in the applied force allows the drill point of the screw to easily penetrate the workpiece. Additionally, reducing the RPM can further improve the performance of self-drilling screws and allows the user to push harder.

High Temperature Stability

Drilling produces friction, which produces heat. A drill point that generates a great deal of heat will fail quickly. This can be controlled by the amount of force applied when drilling as well as the speed of the RPMs on the drill motor.

Drilling Temperature

There are several factors that influence the drilling temperature each of which can be controlled during the application. The RPMs on the motor can be controlled by using the correct settings of the motor to fit the type of material to be drilled and the point of the self-drilling screw.

One of the common errors made when installing a self-drilling screw is the tendency to apply extra force to push the screw into the material. Unfortunately, the application of force can increase the amount of heat created by the screw.

The first consideration regarding the use of any self-drilling screw is the type of material into which it will be injected. Selecting the proper self-drilling screw can prevent a great number of problems especially ones related to the creation of heat during the drilling process.

Applied Force

Reducing the amount of applied force can significantly remove many of the problems associated with connecting two materials. self-drilling screws are designed to penetrate several materials and connect them rapidly and efficiently. Their design, shape, and configuration has been engineered to fit certain materials effortless, without the need for extra pressure or force.

Revolutions Per Minute (RPM)

Another common error in a construction or production operation is to speed up the process. In the case of attaching screws, it may mean increasing the speed of the drill motor such that it produces higher RPMs. Each self-drilling screw is designed to be inserted at a particular speed, which is specified by the manufacturer. Attempting to insert them at a speed that is not recommended may cause their failure.

When using a stainless steel self-drilling screw, RPMs of 600 to 900 is recommended. Some manufacturers apply a coating to their screws to help them withstand the torque that is applied.

Each type of self-drilling screw has a set of requirements to ensure their successful use. These recommendations have been tested by designers and engineers to guarantee their products will perform up to quality standards.
