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)
