WIHA 31395 11-piece insulated 1/4" metric socket box set

Professional insulated socket set

The Wiha 31395 box set supplies eleven 6-point metric sockets ranging from 5 mm to 14 mm on a 1/4 inch drive. Chrome vanadium steel with a chrome finish gives corrosion resistance for workshop use. The insulated T-handle design protects users when working near live circuits up to the rated voltage. Electricians and maintenance technicians who need certified insulation will find the range covers common fastener sizes.

Fits standard 1/4 inch drive workflows

Each socket locks onto a 1/4 inch square drive so the set works with existing ratchets, extensions and torque tools. The T-handle grip allows high torque by hand without a separate ratchet, freeing bench space and reducing tool count. Deep or flex sockets are not included, so recessed or angled fasteners need supplementary pieces. The compact box keeps the eleven pieces organised inside a tool chest or service vehicle.

Sustained torque without impact rating

Chrome vanadium steel handles repeated hand-applied torque on stubborn bolts but the set is not impact rated for powered drivers. Insulation integrity remains stable during long jobs because the coating is bonded to the socket body rather than dipped. Heat from prolonged fastening does not degrade the chrome finish or the 6-point geometry. Users needing impact-grade sockets for pneumatic or electric guns should select a different range.
