2-3 Small Screwdriver

Built for tradesmen who need a reliable slotted blade in one specific width, this 3 mm tool handles the fine-pitch fasteners that larger drivers cannot reach. The flat tip seats firmly in narrow screw slots, reducing cam-out and protecting surrounding surfaces from scratches or gouges.

Overall length measures 122 mm (approximately 4.8 in), giving you enough shaft to reach recessed fasteners while the compact profile keeps the tool easy to control. Total weight is just 20 g, so carrying it in a breast pocket or clipping it to a tool roll adds virtually no burden to your loadout.

Common tasks that call for this size include tightening hinge screws on eyeglass frames, adjusting terminal-block connections, seating set screws in small assemblies, and working on smart-home devices such as a ring screwdriver task on a doorbell faceplate. Watchmakers and electronics technicians will appreciate the controlled torque that a dedicated single-size driver delivers over a multi-bit handle with play in the chuck.

Because this is an individual driver rather than a bundled set, you can slot it into an existing kit, replace a worn favorite, or stock several at different workstations without paying for tips you will never use. Pair it with other Teng Tools drivers to build a personalized collection matched to the fasteners you actually encounter on the job.
