Different types of screws are available in the market for fastening materials together. However, of all these screw types, self-tapping screws stand out as being exceptional.
If you are familiar with using screws to hold materials such as woods and metals, you should know that most times it is usually required that a hole is firstly drilled in the materials before fastening them together with the screw.
In contrast, self-tapping screw, also known as Self threading screw is unique because you do not necessarily need to drill an initial hole on either material.
A self tapping screw creates a pilot hole while it is being driven into the material. This exceptional property of self tapping screws enables them to offer higher effeciency when used, especially in the manufacturing and construction industry.
They conserve time and energy by eliminating some of the rigorous installation processes. In this article, we will walk you through the types and various uses of self tapping screws you need to know.
Two basic types of Self tapping screws are available in the market. Firstly, there is the Thread forming screw and secondly there is the Thread tapping screw.
Thread forming screws do not have pointed tips and so would not be able to drill a pilot hole by themselves. Therefore, before making use of these screws, you need to firstly drill a pilot hole on the material by yourself.
Thread forming screws are usually used to hold plastic materials together. They are specially designed to grip the materials tightly together. You should however be careful when using them in order not to apply too much pressure that will crush the plastic materials.
Unlike Thread forming screws which require a pre-drilled hole, Thread Tapping screws actually drill their own pilot hole during the fastening process. This makes the fastening process relatively faster.
However, using Thread Tapping screws may require more of your efforts as you need to apply more pressure on the screw to drill its own pilot hole through the material which most times is a metal.
The Uniqueness of self tapping screws among many other types of screws make them applicable in many areas.
