2-2.5 Hex Mini Screwdriver

When a job calls for a 2.5 mm metric hex fastener and nothing else, reaching into a bulky multi-piece set wastes time and drawer space. This individual Teng Tools driver delivers exactly the right tip in a compact 122 mm (4.8 in) package that weighs just 24 g (0.8 oz).

The hex profile engages all six flats of the fastener recess at once, spreading the turning load evenly and helping protect small socket-head cap screws from rounding. That even engagement also gives you clear tactile feedback — you feel the tip seat before you turn, reducing the chance of a slip in a cramped enclosure.

Professionals who service electronics racks, optical benches, laboratory instruments, drone airframes, and precision mechanical assemblies will find the 2.5 mm metric tip is one of the most frequently needed sizes in the small-hex range. Buying it individually means you can replace a lost or worn driver without repurchasing an entire kit, or you can assemble a personalized selection of only the sizes your work actually demands.

The overall length keeps the tool maneuverable in tight spaces — behind panels, inside chassis, and between closely spaced components — while still offering enough handle surface for a secure, controlled grip. Light enough for all-day pocket carry, it stays with you from the bench to the field without adding bulk.

Add this 2.5 mm driver to your precision tool roll and keep a spare in your go-bag so the right size is always within reach.
