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.

The structure of the self-tapping screw with a press washer with a drill is strong enough to withstand high loads.

Application of self-tapping press washer drill:

Self-drilling screws with a press washer is specialized in fastening sheet metal products.

Their main scope includes all types of construction installation of profiled metal sheets. The special design of the head does not allow it to penetrate deep into the material.

erection of a metal crate under the plasterboard during internal construction work fastening of additional elements for buildings made of sandwich panels, ventilated facades for external cladding of buildings the formation of window slopes, various ebbs and other works during facing works installation of fences, fences with metal bearing elements (for example, metal pipes)

Installation of ventilation systems:

All of these areas occupy a significant share in construction, which means that the volume of consumption of self-tapping screws with a pressure washer is large.

The shape of the self-tapping screw with a drill does not have pointed elements, which means it does not leave scratches and chips on the surface of metal products during the installation of fasteners.
