Countersunk Wood Screw with Pozidriv (PZ) Drive (Fischer PowerFast PZ)
A high-performance steel chipboard and structural wood screw featuring a Pozidriv drive recess, designed for general carpentry, timber framing, and hardware installation.
Pozidriv (PZ) Drive: Designed with a cross-shaped PZ drive recess that provides additional contact points to reduce driver bit slipping and cam-out compared to standard Phillips drives.
Countersunk Head with Milling Ribs: Features an angled countersunk head equipped with under-head pocket ribs to sit flush with wood surfaces without causing splintering.
Shank Reaming Section: Outfitted with an upper shank friction-cutter section above the threads to enlarge the hole, clearing wood debris and reducing insertion torque.
Coarse Wood Thread: Deep, high-pitch thread geometry with a sharp self-tapping point ensures immediate engagement and high pull-out resistance without requiring pre-drilling in softwoods.
