Product Features
Green Anti-Corrosion Coating: Eco-friendly rust-preventative treatment that resists erosion from rain, moisture, and preservative wood chemical solutions, drastically extending the outdoor service life.
Countersunk Head + Under-Head Cutting Ribs: Easily cuts wood during tightening to allow the screw to fully countersink, achieving a flat surface with no protrusions while balancing aesthetics and anti-corrosion performance.
Square Drive: Resists slipping and cam-out during driving, capable of bearing larger torque. It pairs with power tools to achieve higher installation efficiency.
Hi-Lo Thread + Cutting Sharp Point: Taps into wood without the need for pre-drilling. The hi-lo thread design balances low resistance with a strong gripping force while effectively preventing the wood from splitting.
