Why this one
Short 40 mm body
At 40 mm (1.6 in) overall, the compact body fits spaces that longer accessories can't reach, such as behind flanges and inside machinery housings.
Hex drive shank
The drive is a 10 mm or 12 mm hex shank, for use with matching bit holders, ratchets and adapters.
Sizes 5 to 19 mm
Sold individually as single allen bits in sizes from 5 to 19 mm, so you can replace a worn or missing one.
Made to DIN 3126
Designed and manufactured to DIN 3126 / ISO 1173, for fastenings with a hexagon hole.
Read the full description
When heavy-duty metric fasteners call for a 19 mm tip, this Teng Tools accessory answers with a precise hex profile and a 10 mm hex drive shank built for serious torque. The shank seats into standard wrenches, ratchets, and adapters, so you can put it to work immediately with the tools you already own.
At 40 mm (1.6 in) in overall length, the compact body fits into spaces that longer accessories cannot reach. Structural bolt patterns tucked behind flanges, recessed hardware inside machinery housings, and cramped under-vehicle fasteners are all accessible with this short-profile piece.
Weighing 70 g, the tool has enough substance to handle the loads that come with larger hex engagement points. The proportioned shank and tip help distribute stress evenly, reducing the chance of flex or deformation during heavy pulls.
Sold as a single allen bit, this accessory lets you replace a worn or missing size without purchasing an entire kit. Stock the sizes that see the most action in your shop and keep spares on hand for the fasteners that matter most to your workflow.
