Galvanized steel, blue passivated (A3K). Raised countersunk head in flat design with AW drive.
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 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
Included: 1 bit
NoticeContact 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.
