Full-Thread Countersunk Wood Screw with Pozidriv (PZ) Drive (Fischer PowerFast II PZ)
A high-performance steel wood screw featuring continuous full-length threading and a Pozidriv recess, engineered for high-tensile timber connections, hardware mounting, and structural wood assembly.
Full-Length Coarse Thread: Continuous threading along the entire shank provides maximum pull-out resistance, high shear load capacity, and strong clamping force across joined timber members.
Pozidriv (PZ) Drive: Designed with a cross-shaped PZ drive recess that offers extra contact points to reduce driver bit slip and cam-out compared to standard Phillips drives.
Countersunk Head with Under-Head Ribs: Sinks flush into timber or pre-countersunk metal brackets without tearing the surface or causing wood splitting.
Aggressive Self-Tapping Tip: Sharp piercing point with active thread geometry enables fast bit engagement and instant bite without requiring pre-drilling in softwoods.
