Self drilling screw, also known as sheet metal screws or dovetail screws, are a type of high-hardness self-tapping screws. The unique drill tail or pointed tail design at the tail gives it the ability to directly screw into materials without pre-drilling holes. The powerful functions of drilling, tapping and locking greatly simplify the installation process and effectively save construction time and labor costs.

* High Quality 410 Stainless Steel, Stainless Steel with Superior Rust Resistant Ensure, More Solid and not Easy to Break;
* It is wood drill tail screw, mainly used in steel structure caigang watt fixed can also be used for fixing the simple
construction of the sheet material;
* How to use? Self-Drilling Screws, eliminate the need for a pre-drilled hole. The length of the drill point determines the
material thickness which the screw can reliably penetrate. When selecting a self-drilling screw design, it is important to
consider the material thickness and type of materials to be joined. These stainless are great to use in environments that are damp;
* Modified Truss head is extra wide with a low-profile dome and integral round washer, Phillips driver designed to prevent
over-tightening.
