Self tapping screws description
There are various types of self-tapping screws, including round head (semi-circular head), flat round head, pan head, countersunk head, semi-countersunk head, cylindrical head, hexagonal head, hexagonal flange head and so on. Different head shapes are suitable for different application scenarios and installation needs. For example, countersunk head self-tapping screws allow the screw head to be flush with the mounting surface, which is aesthetically pleasing and doesn't protrude; pan head self-tapping screws provide a larger contact area, which can better distribute pressure.
Self tapping screws working principle
The threads of self-tapping screws have a high degree of hardness and a sharp tooth shape. When a self-tapping screw is screwed into a material with a tool, its tip first cuts into the material, and as the screw rotates, the threads extrude and cut the corresponding threaded grooves inside the material like a cutter, forming a tight threaded connection between the screw and the material, thus realizing the purpose of firmly connecting two or more objects together.
