Precision hex nut driver set 26390

The Wiha Tools 26390 set contains seven precision hex nut drivers sized from .7 mm to 3 mm. Black handles identify each driver and provide a secure grip for detailed work. The round shank design transfers torque efficiently into nuts and bolts. This compact kit fits easily into a toolbox or service bag.

Electronics technicians and hobbyists

Technicians servicing small electronics, instruments or models will appreciate the fine size range and precise fit. Builders who need larger drive sizes or impact-rated tools should look at a different set. The drivers are intended for hand torque only, not powered applications. They suit controlled fastening rather than heavy assembly.

Seven-piece range from .7 mm to 3 mm

The .7 mm to 3 mm span covers the most common precision hex fasteners found in compact devices. Missing sizes outside this interval mean the set cannot address larger bolts or smaller micro-fixings. Buyers must verify their fastener sizes fall within this window before purchasing. No other specifications determine compatibility.

Questions about this item

What hex sizes does the .7 mm to 3 mm range cover for everyday fasteners?

The set spans .7 mm up to 3 mm across seven drivers, covering the small hex nuts and bolts found in electronics, instruments and fine mechanical assemblies.

How does the round shank design affect torque transfer on these nut drivers?

The round shank seats fully in the fastener slot, giving direct torque transfer without the slipping that can occur with shorter or shaped shanks.

What handle diameter and length should I expect for the black precision handles?

Each driver has a compact black precision handle sized for fingertip control in tight spaces, matching the .7 mm to 3 mm tip range.
