Klein Tools 20-in-1 Impact Driver Set, SAE Sizes with Adjustable Screwdriver

KLEIN TOOLS 32303HD is a 20-in-1 screwdriving and nut-driving set with an adjustable-length screwdriver and impact-rated components for demanding fastening work.

• 20-in-1 format with 13 screwdriver bits, six nut setters and a 1/4-inch bit-holder — brings multiple fastening options together in one tool.
• Detachable, impact-rated blade — lets you use the blade as an impact-driver attachment.
• Six SAE nut-driving sizes from 1/4 to 9/16 inch — covers a range of common nut-fastening needs.
• Industrial-strength bits stored in the handle — keeps the bits together and accessible.
• Bit selection includes Phillips, Slotted, Square, TORX and Combo styles — supports different screw head types.

For jobs that call for both screwdriving and nut driving, this set combines the working tool and its bit selection in one handle. Its adjustable-length screwdriver suits fastening tasks that benefit from changing the tool’s reach, while the detachable blade adds an impact-driver option for tougher driving applications. The set is made for convenient changes between common nut sizes and screwdriver bits, without carrying multiple separate screwdrivers.
