Countersunk Structural Timber Screw with Torx/TX Drive (Fischer PowerFast / Construction Screw)
A high-performance steel structural wood screw engineered for heavy-duty timber framing, solar mounting rafter anchorage, and general wood construction.
-
Torx / Star Drive (TX): Features a deep Torx drive recess in the head that prevents cam-out and ensures maximum torque transmission during high-speed installation.
-
Countersunk Head with Milling Ribs: The flush countersunk head includes under-head milling ribs that seat cleanly into the material surface without splintering the wood.
-
Shank Cutter / Reamer Thread: Outfitted with an upper shank reaming section above the lower coarse thread to clear wood dust, reduce driving resistance, and prevent timber splitting.
-
High-Pitch Cutting Thread: Deep, sharp wood threads with a piercing tip enable fast engagement and strong pull-out resistance without requiring pre-drilling in softwoods.
