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


Therefore considerably reduced time and effort



Exact drilling diameter for each screw connection


  • Resulting in minimisation of thread tolerance

  • Always an optimum connection


Prevents installation errors



AW drive system:


  • Enhanced torque transmission

  • Longer service life

  • Optimum centring

  • Better mounting output thanks to fatigue-free screwing in; the required contact pressure for transmission of the torques is considerably lower

  • Largest possible contact surface of bit in screw drive

  • Even force distribution prevents damage to the surface-protection coating and therefore ensures better resistance to corrosion
Notice
  • Contact pressure during use approx. 100 N, screw in with depth stop if necessary

  • 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.
