Klein Tools 646-5/8-INS 5/8-Inch Insulated Nut Driver with 6-Inch Hollow Shaft and Cushion Grip Handle

Great quality nut driver. This thing is sturdy and the insulation seems really good. I have been using it on the job a couple weeks now and its holding up to daily abuse pretty well. The handle is comfortable and i like the feel of it.

Every Klein tool I own has met my needs & continues to be used in the field (and it’s rough for tools in my work). Can’t go wrong w/ Klein.
