black screw self tapping

Are you ever frustrated to death when you want to screw a normal screw into a hard surface? It can take a long time, and be extremely challenging! Which is WHY black screw self-tapping technology is such a handy tool! DFG Guyi self-tapping screws complete almost all assembly jobs with a speed and effort never achieved before.

Discover the power and convenience of self-drilling black screws.

The neat feature of black screw self threading is you can afford to not use a drill. Usually if you want to put in a screw, you have to create a hole first. With these special screws, however, you don’t have to worry about that! The screw itself creates its own hole as it, so you can get right to work. This allows you to use these screws for practically any project, and makes life much easier and faster.
