Specification

Galvanized steel, blue passivated (A3K)

Drilling, threading, screwing-in — all in one work step

Therefore considerably reduced time and effort

Exact drilling diameter for each screw connection

This minimises the thread tolerance thereby always ensuring an optimum connection

Prevents installation errors

Notice

Drilling screws must be processed with a suitable drill driver (e.g. cordless drill driver with depth stop)

The use of impact screwdrivers is not permitted

Drilling screws must be attached perpendicular to the surface of the component

Galvanized drilling screws may only be used where dampness is not to be expected. For fasteners with a construction approval, the approval, and in particular Part 2 "Special regulations", must always be observed.

Application

Application area

Especially suited for use in ventilation systems and air-conditioning technology

Hexagon head with slot for quick loosening in case of repairs
