A box of 200 high-performance 5.0 x 80mm woodscrews is an extra-long structural timber fastener engineered for deep embedding and high load-bearing wood-to-wood fixings. Featuring a double-countersunk head with self-countersinking ribs, razor-sharp partial threading, and a split-resistant cut point, it drives smoothly without requiring pre-drilling in softwoods. The generous 80mm length combined with a heavy-duty 5.0mm gauge delivers maximum pull-out strength and clamp-down force, making it ideal for joining thick timber sections, anchoring timber studs, securing heavy joists, and structural site framing.
