Wiha Tools 32276 1/2 in 5.0 in insulated nutdriver

Insulated 1/2 in nutdriver for live electrical work

The Wiha Tools 32276 is a solid-round insulated nutdriver with a 1/2 in tip and a 5.0 in shank. It is built for electricians and technicians who need to access fasteners on energised equipment up to the rated voltage. The yellow and red insulation provides clear visual identification of the protective layer. This hand tool is not magnetised and does not hold the fastener automatically.

Check your fastener size

The driver fits a 1/2 in fastener and requires a bolt clearance of 5/16 in. Verify that the nut or bolt head matches this exact size and that the surrounding space allows a straight shank of the stated length. The tool carries a California Proposition 65 warning for cancer and reproductive harm. It is not ESD safe and has no magnetic tip for fastener retention.

Insulation handles normal use without extra bulk

The solid shank and moulded insulation add minimal diameter so the driver reaches recessed fasteners in panels and junction boxes. No moving parts or cooling are involved, so operation is silent and there is no power draw. The yellow and red finish resists abrasion during daily hand use and allows quick visual inspection of the insulation integrity.
