The tool features a one-step installation design, capable of completing fastener fixing and tightening simultaneously. No separate holding is required when applying thrust, greatly reducing finger fatigue and enabling easy installation of decking boards. It can precisely fix fasteners, ensuring uniform deck spacing. The prominent nose cone design ensures accurate alignment with the screw head every time, eliminating the need for aiming and saving time. The improved tool is made of harder polymer material, with the nose cone connection structure reinforced to significantly extend service life. Detailed designs focus on practicality: the tool secures fasteners at a 4° slight angle, facilitating smooth insertion of the next decking board. Installation can be completed without secondary tightening, saving nearly half the time. The surface is treated with skin-friendly scrub, ensuring comfortable grip. The angle-adjustable handle can be pushed and pulled from multiple angles, adapting to different usage scenarios and installation habits. A star drive bit is equipped at the bottom for convenient use.
