Self tapping screw and its industrial application

Metric fastener is a very important engineering material, which has been used in many applications in different fields. Many industries use various types of Metric Fasteners, such as construction, wood processing, mobile and aerospace, and electronic equipment production.


However, in this particular content, I will introduce metric thread forming screws in particular. These are screws used to form material or base material around the hole until they are wrapped around the thread. As opposed to other metric screws, they do not remove any parts from the joint.


How do self tapping screws work?


In layman's terms, screw forming screws force the substrate or material to fit into its thread. The process is similar to self tapping screws (self tapping screws remove debris from the material), but they deform the substrate only by bending the substrate to the mating position without removing any of the joints.


application area


Metals or metallic materials - they can be used in a variety of metal materials, such as plate steel, sheet steel, non-ferrous metals and light metals; they can be used repeatedly (reuse).

Nylon and plastics - made from non-metallic materials, including acetals, polycarbonate, PVC and polypropylene.

Wood or wood material - re also has some types that can be specifically used for wood processing, such as in furniture and construction (e.g. m78007-ka18x5 Pt oval head steel zinc wn1412)

Security Screws: Safety Is At Risk Even In Small Stuff

In a world where trust is slowly diminishing, we have become frenetic in handling and keeping things that are significant. But Mother Theresa once said, "Be faithful in small things because it is in them that your strength lies." There's passage reminding us that folks who can't be trusted with small things are people who can't be trusted with big things. Perhaps it can also be said that if we can't trust some literally small things, we can be broken big time. Don't discount the small things for it might be the cause for your serious problem. This also applies with household equipment such as cheap stainless steel security screws. Never dare to belittle the function of small tools chiefly if they have great specifications. Thanks to the genius minds behind screws that are designed to hand a superior level of safekeeping than your standard screws or fasteners. Technically, this innovation was created to avoid crimes like theft and robbery. These gears guara...

Choose a manufacturer specializing in the production of combined screws

 There are many kinds of electroplating of iron combination screws: ordinary and environmentally friendly. For example: color zinc, generally called red color. White zinc, black zinc, white nickel. Blue zinc. There are environmentally friendly color zinc, environmentally friendly white zinc, and environmentally friendly blue zinc. Environmentally friendly white nickel. There are more advanced ones. Nickel on copper, nickel in brine. Tools/Materials Screw wires, iron screw wires include 1010, 1018, 10B21, etc. Stainless steel screw wires include SUS201, SUS304, etc. Steps/Methods The requirements for the material of the combined screw depend on which material is required, whether it is iron or stainless steel. What is the national standard number of the combination screw? There are GB9074.8 and GB9074.4. There are GB9074.13 and so on. The mechanical performance and strength requirements of the combined screw need not be hardened. The level requirements are divided into 4.8 and 8.8 l...

Is the material of stainless steel screws magnetic?

There are many types of materials for making stainless steel screws, and they can be divided into several categories according to the structure at room temperature: austenitic type: such as 304, 321, 316, 310, etc.; martensite or ferrite type: such as 430, 420, 410 Wait;   Austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will result. In this way, 304 stainless steel will have weak magnetic properties.     After 304 stainless steel is cold worked, the structure will also be transformed into martensite. The greater the degree of cold working deformation, the more martensite transformation and the greater the magnetic properties of the steel. Like a batch of steel belts, Φ76 tubes are produced without obvious magnetic induction, and Φ9.5 tubes are produced. Because the bending deformation...
