Fasteners for metal have a small inter-ridge distance or fine threads. Metal is the most dense material widely used in construction. When screwing a self-tapping screw into various profiles or metal sheets, it is necessary to fix the hardware, which is achieved due to a small (frequent) step. There is no fear that the self-drilling screw will “grind” the metal into which it is screwed. On the contrary, the pitch of a wide-threaded screw may be larger than the material itself to which the structure is attached.
The thread on the self-tapping screw(modified truss head self drilling screw ) is two-way, that is, cut in the form of two separate turns running at equal distances from one another.
The drill allows you to screw the hardware into the steel sheet without pre-drilling. As a result, a high-quality reliable connection when working with elements up to 2 mm thick without the use of a drill.
