Stainless steel SUS305J1 deck dedicated screw

[Features]
· Easily drives into even hard decking materials without the need for a pilot hole.
· Reduces screw cutting, head slippage, bit hole damage, and rust generation.
· The screw tip and center part have a special shape for easy driving.
· Uses a special flexible screw head that sinks into decking materials easily.
· Without forcing the head in all at once, stop at the screw thread part or use an impact driver to pull back about 1 cm, then remove shavings and powder before driving the screw in again.
· When using with ultra-hard materials such as IPE, jarrah, and lophira alata, a high torque impact driver is recommended.
