Particle board screw ASSY^® 3.0

Self-countersinking head

• It countersinks anywhere


• 2 processes in one, screwing-in and countersinking


• Less protruding shavings as compared to wings under the head


• Prevents surfaces from cracking, splitting, breaking up


• Screws even into window construction fittings without damaging the coating (as used to happen with the old protruding wings)

Reamer

• Protects the tools


• Reduces friction during screw-in by 40%


• Less stress on electrical tools (longer service life)

Tip with ring thread/tip with counter thread

• The right tip reduces cracking


• Reduces cracking, especially when used near edges


• Reduces tightening torque


• Horizontal ring punching effect: collects shavings during screw-in

Asymmetrical threading

• Fastens lightly


• Less effort required for tightening – optimal penetration


• 50% savings in time


• Single thread on small sizes: increases torque while tightening and increases shear strength

AW drive

• Perfect fit between the driver and the screw head


• Optimal force transmission thanks to the perfect geometry of the drive surfaces


• Lasts longer


• Optimal and rapid centring


• Optimal contact surfaces reduce expulsion forces (preventing the bit from coming out)


• Reduced wear: even distribution of force prevents the surface coating of the screw and the screw head from being damaged
