Insulated 8.0 mm nut driver

The Wiha Tools 32221 is an insulated nut driver with an 8.0 mm hex opening designed for electrical work. Its solid round shank measures five inches and the overall length is nine and a half inches. The red and yellow handle provides high visibility in a toolbox or pouch. It is rated for 1,000 V AC and 1,500 V DC.

Build quality and daily use

The insulated coating on the shank protects the user when working on live circuits up to the rated voltages. A solid round shank resists flexing while reaching recessed fasteners. The bright two-tone handle allows quick identification among other tools. The 8.0 mm hex fits standard metric nuts and bolts directly.

Upgrade considerations

This driver replaces a non-insulated nut driver when electrical safety standards require voltage-rated hand tools. The jump is worth it for electricians and technicians who regularly service panels or equipment where de-energising is not practical. It is not suited for tasks needing a different hex size or a non-insulated slim profile.
