Self-tapping screws are one of the most commonly used types of fasteners in the industrial and scientific sectors. These screws are used to join two or more materials together, and they can be found in a wide range of applications, from automotive to medical.
The main difference between self-tapping screws and other fasteners is that these screws do not require a pilot hole. The self-tapping screw has ridges along its shank which form threads in the material when it is screwed in. This means that it is simple to install, as no pre drilling is required.
There are different types of self-tapping screws available for different applications, and the choice of which screw to use is largely based on the type of material that is being joined. For example, self-tapping screws are used commonly in wood applications, whereas in metal working self-tapping screws with a larger diameter and higher thread count may be used.
These screws are usually made from steel or stainless steel, although other metals such as brass and aluminum are also used. In addition to the choice of material, self-tapping screws come in different head shapes, drive styles and thread styles, so the right type of screw can be chosen to match the application.
When installing self-tapping screws it is important to pay attention to the torque setting and ensure that the right amount of torque is applied. If the screws are over-tightened this can cause too much stress on the threads, which can lead to fatigue cracking, or in extreme cases, failure of the joint.
Self-tapping screws are a simple and cost-effective way to fasten two or more materials together and they are widely used in the industrial and scientific sectors. When choosing the correct screw for the application, it is important to consider all aspects of the project, from the material to be joined and the desired torque setting, in order to get the best results.
