Easy and quicker countersinking thanks to innovative, patented thread geometry. Several concave threaded strips allow the wood to be penetrated easily and chips to be removed. Duo countersunk head with milling ribs beneath the head for tidy countersinking. The cutting slit in combination with the serrated blade facilitates chip-free screwdriving, even around the edges.
• A deeper thread and smaller screw-in torques compared to conventional particle board screws
• Patented thread geometry, easier and quicker countersinking
• Chip-free screwing, even around the edges
• Wood can be penetrated easily thanks to the concave threaded stripes
• Excellent performance, even in hard wood
• Connects the wood, instead of splitting it
