This Klein Screwdriver / Nut Driver allows for one-handed driving, with seven sizes in one tool
Strong, rare earth magnets (7mm, 8mm, 9mm, 10mm and 12mm sizes) securely hold nuts and bolts
Spring coil (11mm and 13mm sizes) holds nuts and bolts in place without the use of magnets
Hollow shafts (7 mm, 8 mm, 10 mm, 11 mm and 13 mm sizes) for driving nuts deep onto bolts or threaded rod
Heavy-duty handles and shafts exceed the torque performance of standard nut drivers
Wrench-assist on handle for added torque on tough jobs
Colour-coded bands for easy identification
