11/32 in magnetic nutdriver

The Klein Tools 646-11/32M is a hollow round shank nutdriver with an 11/32 in tip size and a magnetized tip to hold fasteners. It is designed for technicians and tradespeople who drive SAE hex nuts and bolts in electrical, HVAC or general maintenance work.

Replaces worn or non-magnetic drivers

A magnetized tip reduces dropped hardware when working in panels or conduit. The 6 in bolt clearance lets you reach recessed fasteners that a standard screwdriver cannot engage. Upgrade when your current driver slips or lacks the reach for deep-set nuts.

Simple hand-tool installation

No power source or calibration is required; select the matching 11/32 in fastener and apply torque by hand. The cushion grip improves control but the tool is not insulated and is not ESD safe, so it must not be used on live circuits or static-sensitive assemblies.

Questions about this item

What bolt clearance does the 11/32 in nutdriver provide?

The hollow round shank gives 6 in of bolt clearance so longer fasteners can pass through the driver without bottoming out.

How do you use the magnetized tip correctly when installing a fastener?

Place the nut onto the magnetic tip, align it with the bolt threads, and turn the cushioned handle — do not strike the handle or use it as a pry bar.

When should the nutdriver be replaced due to tip wear?

Replace the tool once the 11/32 in hex opening rounds out or the magnet no longer holds the fastener securely during positioning.
