pias^® drilling screw, raised countersunk head with AW drive

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

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

Optimum torque transmission due to AW drive

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
