Product Description

Self Drilling Screw vs Self Tapping screw:

1. Appearance:

The lower part of the thread of the drilling screw comes with a flat drill bit, which is similar to a drill bit, mostly with
double line fine thread. The thread of the self-tapping screw does not have a drill tail below, it is a smooth thread.
Self-tapping screws are two types, including fine thread and coarse thread.
2. Application:

Self-tapping screws are used on materials with non-metals or soft metals. It can drill on the fixed material to make them fit
closely with each other. Drilling screws are mainly used in mental, such as light-steel structures. They are more widely used in
rigid structure workshops and other buildings than self-tapping screws.
3. Usage:

Self-tapping screws with the pointed tail, and there is no drill part at the tail. An electric drilling gun must be used to drill
into the metal material in order to make a prefabricated hole in the object, and then the self-tapping screw can be tapped. The
self-drilling screw has its own drill tail, which makes it easily screw into steel plates, wood etc. That greatly saves
installation time.
