Premium Nut Driver Set for Pro-Grade Jobs

The Klein Tools 647M Magnetic Nut Driver Set brings seven drivers designed to handle everyday fastening tasks with precision and ease. Each driver features a robust design that emphasizes control, durability, and reliable magnetism so you can start fasteners and drive with confidence. The set’s hollow shafts enable easier work with longer bolts, reducing the need to reposition your hand mid-task. Note that the 3/16" size uses a slightly different shaft construction, while the rest of the set benefits from full hollow shafts for versatility at the workbench or on-site.

Why it’s crafted for real-world use

These drivers combine practical features that translate into smoother workflows. The donut-shaped magnetic tips are designed to hold fasteners in place, saving you time and reducing dropped parts. Chrome plating guards against corrosion in tough environments, while Cushion-Grip handles deliver a comfortable, torque-friendly grip that helps you maintain control through extended sessions. Internal flanges provide a solid, twist-resistant anchor to the shaft, so the tool stays aligned as you apply torque.

  • Nut drivers' full hollow shafts (except 3/16-Inch) facilitate work on long bolt applications
  • Rare-Earth magnetic tips hold fasteners in place for easy one-handed setup
  • Cushion-Grip handles improve torque and comfort; color-coded domes aid quick size identification
  • Internal flanges provide a solid, twist-resistant shaft anchor
  • Made in USA; chrome-plated shafts help prevent corrosion
  • Set contains Cat. No. 646-3/16M, 646-1/4M, 646-5/16M, 646-11/32M, 646-3/8M, 646-7/16M, 646-1/2M

What you get goes beyond a basic toolkit addition. This set is built to support professional workflows and dedicated DIY projects where dependable fastener handling matters. While results depend on task specifics, the combination of magnets, balanced weight, and shaft geometry offers a practical pathway to smoother assembly and maintenance routines.
