Common types and usage methods of self tapping screws

Today, the editor of Nissan Fasteners will introduce to you the knowledge of "common types and usage methods of self-tapping screws". The thread on the screw has a self-tapping performance, which can connect two thinner metal components. Due to its high hardness, it can be directly screwed into the metal components that have already been pre-drilled
In order to complete the fastening effect, the holes are drilled.
Common types
1. Head shape (head shape)
This type of screw has various head shapes, such as cylindrical head, spherical cylindrical head, half-round head, flat round head, pan head flange (with gasket), countersunk head, half countersunk head, hexagonal head, hexagonal flange head, etc.
2. Wrenching method (slot type)
The so-called twisting method, in simple terms, refers to the method of twisting the screw head when installing and tightening screws. At present, it can be roughly divided into two types, one is the external trigger and the other is the internal trigger. Usually, the torque of external tightening is greater than that of internal tightening.
External wrenching mainly includes hexagonal, hexagonal flange face, hexagonal flange, and hexagonal flower shape, etc; Internal wrenching mainly includes straight groove, cross groove Z-type, cross groove F-type, square groove, internal spline, hexagonal flower shape, internal triangle, internal hexagon, hexagonal groove, etc.
3. Thread type
At present, there are various types of threads for this screw on the market, including not only common threads such as wide tooth threads and machine threads but also special threads such as drywall threads and fiberboard threads.
In addition, threads can also be divided into single-head, double-head, multi-head, and high and tooth doublehead.
4. End Style (Tail)
The end styles can be mainly divided into two types, one is the tapered end and the other is the flat end. According to the needs of use, other special parts such as grooves, notches, incisions, etc. are often added to the screw in part at the end. In some standards, the forms of tapered or flat ends can be subdivided into several types.
Usage
This screw has a wide range of uses in daily life, but even so, there are still many people who are not familiar with its usage. In fact, when using it, a screwdriver or drill can be used to drive it in. Sometimes, an electric hammer can also be used. If it needs to be driven into concrete, an electric hammer is usually needed.
In daily use, people use an electric screwdriver to punch holes, and then install them, which can be said to be very simple and convenient.
The characteristics of this screw are as follows:
It comes with a drill bit, which can be used for drilling, tapping, fixing, and locking tasks in one go through electric tool construction. It is suitable for connecting and fixing thin plates with a thickness of about 6 millimeters.
There are many types of self-tapping screws, and although the usage method is relatively simple when using this screw, everyone must find the suitable type and then use it correctly.
