Product Description

Drill tail self tapping screw is a type of screw with a special design that can be self tapped without the need for pre drilling or threading. The head of a self tapping screw with a drill tail is usually designed with a sharp drill bit, which allows the drill bit to penetrate the material first and form threads inside the material while screwing in.

The characteristics of self tapping screws with drill tails are as follows:
1. Integrated operation: It can achieve the integration of drilling and tapping, simplify the installation process, and improve work efficiency.
2. High efficiency: Suitable for quick installation, especially in automated production lines and large-scale assembly operations.
3. Applicable materials: Usually used for connecting thin metal plates, plastics, wood and other materials.
4. Thread formation: When the screw is screwed in, its thread will form inside the material, and there is no need to prepare a threaded hole in advance.
5. Diverse types: According to different application requirements, there are various specifications and types of drill tail self tapping screws, including different sizes, lengths, head shapes, and thread specifications.

Drill tail self tapping screws are widely used in industries such as construction, furniture, electronic products, and automobile manufacturing, and are one of the indispensable fasteners in modern industrial production. When using, it is important to choose screw specifications that match the material to avoid damaging the material or the screw itself.
