Why this one
Extra long arm
The extended arm can drop into deep cavities and reach past obstructions, and gives you more turning force on stubborn cap screws and set screws.
Ball point tip
The ball point gives access at angles up to 25°, so you can approach a bolt when adjacent hardware or sheet metal blocks a straight path.
Short arm for torque
A regular hex end on the short arm lets you apply higher torque with full contact when it's time to tighten or break loose.
Sizes 1.5 to 10 mm
Made from chrome molybdenum steel and sold individually in metric sizes from 1.5 mm to 10 mm.
Read the full description
Larger metric hex fasteners demand a wrench with serious reach and leverage. This Teng Tools 10 mm individual tool measures 224 mm overall, giving you an extended arm that can drop into deep cavities, reach past obstructions, and apply meaningful turning force to stubborn cap screws and set screws.
The ball point tip lets you approach the fastener at an angle when a straight path is blocked by adjacent hardware, sheet metal, or structural members. That off-axis capability saves you from disassembling surrounding components just to get a clear shot at one bolt.
At 182 g, the wrench is substantial enough to handle the torque loads associated with 10 mm fasteners yet still compact enough to toss into a pocket or belt pouch. It is clearly marked 10 mm so identification is instant, even in low light.
Whether you are replacing a single lost or bent key from a set you already own or stocking your toolbox with dedicated wrenches in the sizes you reach for most, this Teng Tools metric tool delivers the reach, leverage, and angled access that professional work demands.
