Description
Full-Thread Countersunk Structural Wood Screw with Torx/TX Drive (Fischer PowerFast II / Full-Thread Wood Screw)
A high-performance steel wood screw featuring continuous full-length threading, engineered for high-tensile structural timber connections, solar roof hook anchoring, and wood reinforcement.
-
Full-Length Coarse Thread: Continuous threading along the entire shank provides maximum pull-out resistance, high shear load capacity, and exceptional clamping force across wood members.
-
Torx / Star Drive (TX): Equipped with a deep star/Torx recess to ensure slip-free power transmission and prevent driver bit cam-out during high-torque driving.
-
Countersunk Head with Under-Head Milling Ribs: Allows the head to sink flush into timber without splintering the surface or damaging attached metal brackets.
-
Aggressive Self-Tapping Tip: Sharp piercing point with active thread geometry provides immediate grip and minimizes wood splitting without requiring pre-drilling in softwoods.
