WIHA 31391 13-piece metric insulated 1/4" drive socket set

Insulated 1/4" drive socket set

The Wiha 31391 provides 13 pieces of insulated hand tools for metric fastening tasks. Ten standard 6-point sockets cover sizes from 5 mm to 14 mm for a range of bolt heads. Chrome vanadium steel construction adds durability without impact rating. The set suits electricians and technicians working near live circuits up to the rated insulation limit.

Check drive size and socket profile

Verify that your ratchet or torque wrench accepts a 1/4 inch drive before ordering. The sockets use a 6-point profile, so confirm the fastener heads match this geometry. Bolt clearance is listed as 3/8 inch, which may restrict access on longer threads. No deep or flex sockets are included in this box.

Fits insulated tool kits and service cases

The compact box organizes every piece for quick identification on the job site. Insulated handles allow safe use alongside voltage-rated screwdrivers and pliers. Chrome finish resists corrosion in damp environments. The set frees up space by replacing multiple single sockets with one dedicated metric tray.
