Self-tapping screws are used for non-metallic or softer metals without underhole and tapping. That is to say: the hole drilled is a hole that does not need to be tapped, the screws used are different from the general, the head is pointed, the tooth distance is relatively large, and the chipless wire tapping is a bit similar, you can screw it directly without tapping, metal and plastic usually use this method.

Self-tapping screws are mainly used for the connection and fixing of some thinner plates, such as the connection between the color steel plate and the color steel plate, the connection between the color steel plate and the purlin, the wall beam, etc., and its penetration capacity is generally not more than 6mm, and the maximum is not more than 12mm. Self-tapping screws are often exposed to the outdoors and have strong corrosion resistance; Its rubber sealing ring can ensure that the screw is not waterproof and has good corrosion resistance.

Dear, hello, I am happy to answer for you, the difference between self-tapping screws and pointed screws is wood screws, and self-tapping screws are threads. Self-tapping nails have sharper tips and smaller diameters, making them easy to twist. Wooden screws should be thicker, strong connection force self-tapping screws, everyone has seen, generally fingertip thick teeth and hard texture of wooden screws.

Of course, there are also aluminum alloys; Plastic. A special type of self-tapping screw used for opening threads in metal holes is called tapping. Self-tapping screws are used for non-metallic or soft metals, without priming holes and tapping; The self-tapping screws are pointed, so that they can "self-tap", and ordinary screws are flat-headed, with the same thickness.

The difference between self-tapping screws and flat-head screws is that self-tapping screws do not need to tap the holes, and the screws used are different from the general, the head is pointed, and the tooth spacing is relatively large, which is a bit similar to the chipless tapping, which can be screwed in directly without tapping, and the metal and the plastic usually use this method. The flat-head screws are mostly used in CCB's potato construction sites and other projects, and for power dispatching of power systems in hydroelectric power stations. Self-tapping screws:

Generally, it is a kind of screw with a pointed end, thick teeth, and high hardness, and it is also a flat head and a cross opening. Ordinary screws also have flat heads, with the same thickness up and down, and male and inch threads.

<> "Self-tapping screws and wood screws are not the same material, and their properties are different, which need to be confirmed in advance to ensure future use. And what is the difference between self-tapping screws and wood screws.

What is the difference between self-tapping screws and wood screws.

1. The main difference lies in the different tooth types and forms of use, wood screws are specially designed for wood materials, and self-tapping screws are generally connected to iron plates and plastics.

2. Wood screws are one of the types of self-tapping screws, which are usually used for fixing wood, and the main feature of the shape is the wide tooth pitch. One of the ways to distinguish the use of self-tapping screws is to look at the pitch, generally the smaller the pitch, the greater the strength of the substrate attached.

3. The difference between the two is also that the number of teeth is different, the surface hardness is different, and the teeth of self-tapping screws are denser than those of wood screws, and the surface is harder. Self-tapping screws are wider than wood screws.

4. The tooth pitch of the two is different from the angle of the tooth tip and the angle of the tooth pattern.

What details need to be taken into account when using self-tapping screws.

1. When the drywall can be fixed with self-tapping screws, the self-tapping screws can be screwed into the drywall and drilled by itself.

2. The self-tapping screws need to be drilled, tapped, fixed and locked at the same time with special electric tools. Self-tapping screws are usually used on thinner plates to play a fixed role, such as the fixing between color steel plate materials, and the pre-excitation connection between color steel plates and purlins and wall beams.

3. Self-tapping screws are mainly used for the installation of doors and windows. Self-tapping drywall screws are used for connections between drywall, etc. and metal keels. The thread is a double-sell lead blind thread, and the thread surface also has a high hardness, which can be quickly screwed into the keel without pre-punching in the hollow, and then form a connection.

Screws are a kind of industrial necessities that are often used in daily life, and they are a kind of fasteners. The fastening effect of the screw is generally achieved by the circular rotation and friction of the object, and the usual screw is flat-headed. Among the types of screws, there is a pointed screw, which is mainly used for fastening between non-metallic or soft metal objects, and does not need to be punched and tapped during use.

These screws are called self-tapping screws.

Self-tapping screws are widely used in life and industrial construction processes, and more and more often play a role in replacing ordinary flat-head screws, so the development prospects of self-tapping screws are quite gratifying. At present, there are many brands of self-tapping screws on the market, so which manufacturers produce self-tapping screws that are more worthy of the trust of consumers and friends?

1. What are the specifications of self-tapping screws?

According to the diameter of the screw, there are 13 specifications, respectively, the user needs to decide the specification of the screw according to the actual needs when purchasing. In addition, according to the different shape of the head, self-tapping screws can also be divided into three types: round-head self-tapping screws, flat-head self-tapping screws and countersunk self-tapping screws.

Second, how to choose the right self-tapping screw.

1. Look at the type of screw.

According to professionals, there are many types of screws on the market, and different types of self-tapping screws have very different scopes of application, aesthetics and performance characteristics. For example, if the screws used to fix the aluminum alloy are used, it is generally recommended to use flat-head screws.

2. Look at the size of the screw.

From the above article, it can be understood that there are many specifications and models of screws, and the force capacity of different types of self-tapping screws is very different. In the case of the same force, the longer the screw, the better its ability to hold nails, and the stronger the load-bearing capacity, so consumers must choose according to the design standards when purchasing.

3. Look at the quality of the screws.

There are many channels to buy self-tapping screws, and users must go to regular hardware stores to buy when buying, so as to ensure the quality of self-tapping screws. In addition, when purchasing self-tapping sail screws, it is also necessary to check whether the threads of the screws are clear and whether the size is consistent with the specifications, because this is the key to determining the performance of the screws.

Summary. 1. Ordinary self-tapping screws.

The thread is a "self-tapping thread", which is very common in the market, and is also known as a "wide thread".

2. Self-cutting and self-tapping screws.

Compared with ordinary self-tapping screws, self-cutting self-tapping screws have made a lot of optimizations in function, and there are two kinds of threads: self-tapping threads and machine threads.

3. Self-tapping locking screws.

This kind of screw is generally machine threaded, which is generally used to assemble a wrench, and the screw cross-section is triangular, so it is also called a triangular threaded screw.

What is the difference between self-tapping screws and tapping screws.

Hello, happy to answer your questions.

Tapping screws also belong to self-tapping screws. Both are about the same, both are self-tapping.

Tapping screws are generally finger-tipped, coarse-toothed, and hard-textured wooden screws. It also has aluminum alloy and plastic, which is used for non-metallic or softer metals, without priming holes and tapping, and the self-tapping screws are pointed, which can be on the consolidated material, relying on its own thread, will be consolidated "tapping, drilling, squeezing, pressing" out of the corresponding threads, so that they fit closely with each other.

1. The ordinary self-tapping screw thread is "self-tapping thread", which is very common in the market, also known as "wide thread". 2. Self-cutting and self-tapping screws Self-cutting and self-tapping screws have made a lot of functional optimizations compared with ordinary self-tapping screws, and there are two kinds of threads: self-tapping threads and machine threads. 3. Self-tapping locking screws are generally machine threads, which are generally used to assemble wrenches, and the cross-section of the screw is triangular shape, so it is also called a triangular threaded screw.
