9 Piece Metric Allen Wrench Set

Teng Tools delivers a focused metric hex wrench set built for tradesmen who need reliable, organized access to the nine most common metric sizes. Each L-key pivots from a sturdy red folding holder, keeping the full 1.5 mm to 10 mm range together in one compact package that weighs just 249 g.

The keys are made from chrome vanadium steel and carry a chrome finish for lasting corrosion resistance. Whether you are torquing cap screws on a production line, adjusting set screws on a mill, or servicing a bicycle drivetrain, the CrV construction stands up to repeated use without rounding or bending.

Produced to DIN 911, each key features precise flats that seat fully into metric hex-socket fasteners. That tight fit reduces cam-out and protects fastener corners, a detail that matters when you return to the same bolt at every maintenance interval.

The L-key profile gives you two working options from a single tool. Use the short arm for higher torque in confined spaces, or flip to the long arm when you need reach into a deep recess. The folding holder acts as an extended grip when a key is deployed, adding leverage and comfort during sustained turning.

Sizes included: 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm. This metric-only selection eliminates the clutter of SAE keys you do not need and keeps the holder slim enough to carry in a pocket or toss in a drawer without taking up the space of a full case.
