Spectre SPE450Y Advanced Multi-Purpose Wood Screws 4.0 x 50mm Box 200

ADVANCED QUICK-START TIP - Engineered with a specialised razor-sharp point and initial cutting thread that bites instantly into the timber surface. Minimises skating and allows fast, effortless starting without a pilot hole. ANTI-CORROSIVE YELLOW SHIELD - Treated with a high-performance zinc yellow passivated coating. Provides an extra layer of protection against rust and environmental moisture compared to basic bright zinc hardware. ANTI-SPLIT REAMING SHANK - Features a saw-tooth reaming section above the thread that clears the drilled hole as you drive. Reduces installation friction, saves drill battery life, and prevents dense wood from splitting. FLUSH COUNTERSUNK HEAD - Outfitted with a double-countersunk head featuring under-head ribs. Cuts smoothly into the surface fibres to bury itself perfectly flush, creating a pristine, snag-free trade finish. PRECISION POZIDRIV DRIVE - Machined with a high-depth Pozi-drive recess to optimise driver bit engagement. Drastically reduces cam-out slippage, ensuring maximum torque delivery during rapid site fixing.
