Introduction Of Self-Drilling Screws And Self-Tapping Screws

Whether in the manufacturing industry or in daily life, the use of drilling screws and self-tapping screws is quite widespread, which also leads to a lot of people can not distinguish them, or even thinking that the two are the same object, in fact, they are not. As a professional fastener manufacturer, Xinchi Fastener Company will introduce drilling screws and tapping screws and their similarities and differences. We will distinguish the tapping screw and drilling screw from the appearance, use, use method.

What are self-drilling screws?

A drilling tail screw is a kind of fastener, its tail is a drilling tail or pointed tail, so there is no auxiliary processing when using. It can be directly drilled, tapped, and locked on the setting materials and basic materials, greatly saving construction time.

What are self-tapping screws?

Tapping screws, or quick-tooth screws, are quick-mounting fasteners made of steel that have been galvanized and passivated on the surface. When connecting, first make the threaded bottom hole of the connected piece, and then screw the self-tapping screw into the threaded bottom hole of the connected piece.

Common ground between drill screw and tapping screw

They have a threaded body, which can self-penetrate into the connecting piece.

Difference between self-tapping screws and self-drilling screws

The difference in appearance: self-tapping screws are generally pointed, with coarse teeth, a hard texture, with a certain taper, so as to “self-tapping”, but they can not drill. And the head of the drill screw thread has a drill bit that can be drilled.

The difference in use application: self-tapping screws are used for non-metallic or soft metal (such as color steel plate) and other materials with low hardness. It can be on the material being fixed. Through its own thread, it can drill, squeeze, press, and tap out the corresponding thread of the fixed body, so that they fit each other closely. And drilling screw is mainly used for steel structure of color steel tile and plate fixation.

Differences in use methods: The tapping screw is inserted by extrusion to form the corresponding internal thread. They do not need drilling, tapping, or a complete operation, but it is not recommended to drill multiple times, otherwise, it is easy to damage the drilling or slip phenomenon. When using the drilling screw, there is no need for auxiliary processing, it can be directly drilled on the material, tapping, locking, and other complete operations, greatly saving the installation time.
