The Vessel Tool 400PD21U is an 11-piece 2-way power driver set that switches between straight mode for rapid spinning and L-shape mode for high-torque applications. A push/pull collar at the tip transitions the driver between a 1/4-in hex bit holder and a 1/4-in square drive socket receiver without swapping tools. The set includes 5 bits and 5 color-coded sockets covering the most common fastener sizes for automotive work and general maintenance.

• Two operating modes in one body - straight for fast spinning, L-shape for high-torque leverage - reduce the tools needed for mixed fastener jobs
• Push/pull collar switches between 1/4-in hex bit holding and 1/4-in square drive socket use without putting the driver down
• Five color-coded sockets (H8, H10, H12, H13, H14) allow instant size identification in tight or cluttered work areas
• Five 1-in bits included - PH1, PH2, PH3, SL4, and SL6 - covering the most common Phillips and slotted sizes for everyday fastening
• Ergonomic alloy steel handle measures 7-5/8-in long and 1-3/8-in wide for a comfortable, controlled grip during extended use
• Driver and bits manufactured in Japan; includes a storage rail to keep bits and sockets organized between uses

The 400PD21U is built around a dual-mode design that addresses two distinct fastening needs in one compact handle. Straight mode keeps the driver in line with the fastener so you can spin through low-resistance turns quickly, while L-shape configuration provides the mechanical leverage needed to break loose or firmly seat stubborn fasteners. The push/pull collar at the tip handles the transition between bit and socket use in a single motion, making it practical for work that alternates between driver bits and metric hex sockets without interruption.

The contoured handle is finished in black and red alloy steel, offering a secure grip and easy identification on a busy workbench. Color-coded bands on the five sockets speed up size selection when working inside door panels, under dashboards, or in engine bay brackets where visual confirmation matters. Note that double-ended bits or any bit shorter than 1-in (25.4 mm) are not compatible with this driver, and only standard single-ended 1-in bits should be used.

This set suits automotive technicians and maintenance professionals who regularly work with both screws and hex fasteners in confined areas. The 7-5/8-in overall length and L-shape capability make it well-suited for door jambs, interior trim panels, and similar tight-clearance applications.
