Klein Tools 3/8" Heavy Duty Nut Driver with Hollow Shaft is a professional-grade tool designed for driving nuts on threaded rods. It features a through-handle, completely hollow shaft that allows for nut driving on unlimited bolt lengths. This makes it ideal for use in confined spaces or where there are obstructions around the rod. The wrench assist provides greater torque, while the magnetic tips grab any nut appropriately. The color coding helps for easy identification of different sizes, and the classic cushion grip handle provides comfort and control.
