Product Description

 

Drill screws, also known as self-drilling screws, drill tail self-tapping self-drilling screws, dovetail screws, is a special fastener whose tail is designed in the shape of a drill tail or pointed tail, which can be drilled, tapped, and locked directly on the material without pre-drilling. This design greatly simplifies the installation process and saves construction time, especially for the fixing of color steel tiles of steel structures and the fixing of thin plates of simple buildings.
1. Self-tapping and self-drilling performance: no need for pre-drilling, it can be directly drilled, tapped, and locked on the material, which greatly saves construction time.
2. High tenacity and maintenance force: It will not loosen for a long time after combination, and it is safe to use.
3. Economical fasteners: In terms of workability, cost and reliability, self-tapping and self-drilling screws are the best choice.
