Why this one
T handle leverage
The T-shaped crossbar gives high-torque leverage for breaking stubborn fasteners, then works as a grip for spinning the shaft once the bolt is free.
Reaches past obstructions
At 288 mm (11.3 in) long, it reaches past guards, heat shields and wiring without taking surrounding components apart.
Sizes 5 to 14 mm
Sold individually in metric hex sizes from 5 mm to 14 mm, so you can fill a gap or replace one size.
Chrome vanadium shaft
Made from chrome vanadium steel alloy with an ergonomic bi-material handle for higher torque.
Read the full description
When your job calls for one specific metric hex size in the upper end of the range, this 14 mm driver puts precise performance in your hand without the weight and cost of a bundled collection. The T-shaped crossbar offers high-torque leverage for breaking stubborn fasteners, then converts to a fast-spinning shaft grip once the bolt is moving freely.
Measuring 288 mm (11.3 in) from tip to crossbar end and weighing 202 g, the tool reaches past guards, heat shields, and wiring without forcing you to disassemble surrounding components. The hex tip is sized to the 14 mm metric spec, seating flush on every flat so turning force is distributed evenly and fastener corners stay sharp.
Automotive technicians, industrial maintenance crews, and heavy-equipment operators will find this size covers many of the metric fasteners encountered on frame bolts, panel hardware, and structural mounts. Purchasing a single piece means you restock only the size that wore out or went missing, keeping your investment and your drawer space efficient.
Teng Tools builds hand tools for tradespeople who rely on them daily. Add this driver to your service truck, bench, or portable kit and have the exact size ready the moment the job demands it.
