Hexagon Flange Head Drilling screws

Let’s first understand what a drill tail screw is. The drill tail screw can also be called a drill tail self-tapping self-drilling screw, a drill tail screw, a self-drilling screw, a dovetail screw, and the tail of the drill tail screw is a drill tail or a pointed tail. Drilling, tapping and locking can be done directly on the setting material and base material without auxiliary processing, which can greatly save construction time.

Compared with ordinary screws, the combination of high toughness and high maintenance force will not loosen for a long time and it is safe to use. Especially in the combination of construction, construction, residential and other places, self-tapping and self-drilling screws are the best economical fasteners in terms of workability, cost and reliability.

The drill screw is a screw with a self-tapping drill head at the front end of the screw, also called a self-drilling screw.

A screw is a tool that uses the physical and mathematical principles of the oblique circular rotation and frictional force of an object to gradually fasten the mechanism of the utensil.

Screws are a general term for fasteners. There are various types of drill screws such as Φ4.2mm, Φ4.8mm, Φ5.5mm, and Φ6.3mm.

Product advantages:
