General-purpose selection of the most frequently used nut drivers. Full hollow shaft (except 3/16 inch [5 mm]) designed with Rare Earth magnetic tip to facilitate work on long bolt applications. Cushion Grip handles allow for greater torque and comfort. Tip-Ident® quickly identifies nut driver hex orientation and size by color coding the handle ends so you can easily engage the nut driver with the fastener. Internal flanges provide solid, twist-resistant shaft anchor.
