Wiha Tools 32236 Insulated Nutdriver 13 mm 5 in Shank

13 mm Insulated Nut Driver

The Wiha Tools 32236 is a professional hand tool designed for tightening or loosening 13 mm hex fasteners. Its insulated construction provides protection when working near live electrical components up to the rated voltage. The yellow and red colour coding allows quick identification in a busy tool bag. It suits electricians and maintenance technicians who require a single-purpose driver for this specific fastener size.

Installation and common issues

The solid round shank inserts directly into the fastener head without adapters or bits. Because the tip is non-magnetic, the fastener will not self-retain; the user must hold the nut or bolt in place while starting the turn. The 5 in shank length reaches recessed fixings but can limit access in extremely tight cavities. No calibration or setup is required before first use.

Capacity and headroom

The driver fits 13 mm metric fasteners with a 5/16 in bolt clearance, covering a common size in electrical panel and enclosure work. The insulated shaft is rated for the voltages encountered in standard low-voltage installations. It will not engage smaller or larger hex sizes, so a full set is needed for mixed hardware. The tool offers no fastener-holding feature, which slows work on vertical or overhead runs.
