6.5-10mm Flat Head Power Through Screwdriver

Large slotted fasteners on heavy equipment, structural panels, and industrial enclosures demand a driver with reach, leverage, and the ability to take a hammer hit. This Teng Tools 1.6 x 10 mm flat-tip power-through driver delivers all three.

The blade runs the full length of the handle and terminates at a strike cap, so you can hammer directly through the shaft into the screw slot. That transfers impact force efficiently, breaking loose corroded, painted-over, or threadlocked fasteners without splitting the handle or damaging the surrounding work surface.

With a 1.6 x 10 mm tip, this is the widest driver in the Teng Tools power-through family. It fills large slotted heads completely, maximizing torque transfer and minimizing cam-out. Overall length is 325 mm (12.8 in) and weight is 279 g — enough heft for authoritative leverage, yet balanced enough for extended sessions on the job.

The ergonomic handle contour keeps the tool locked in your palm and channels hand force directly into the blade, even when your hands are greasy or gloved. It also resists rolling off inclined surfaces between uses.

Sold as a single driver. Combine it with the other sizes in the Teng Tools flat power-through range for complete coverage of slotted fasteners across automotive, industrial, and facility maintenance work.
