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

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.
