KLEIN TOOLS Impact-Rated SAE & Metric Flip-Socket Set 32933KIT — 12 Sizes, 2x 5" Shafts

The Klein Tools 32933KIT is an impact-rated flip-socket nut driver set that supplies 12 common SAE and metric sizes plus a 1/4" bit-holder and two 5" impact-ready shafts for fast, heavy-duty fastening.

This compact kit combines flip-style nut drivers with impact-rated construction so you can switch quickly between SAE and metric hex fasteners while using an impact driver or Klein quick-connect handles. Every component is engineered for demanding jobsite use, giving you durability and compatibility with modern impact tools. The set minimizes trips to the toolbox by storing multiple sizes on the shaft and providing a secure 1/4" bit-holding option for screws and hex bits.

How does the flip-socket design speed up work?

The flip-socket layout places several nut driver sizes on one shaft so you can rotate to the needed size without changing tools. That saves time when moving between fastener sizes and reduces clutter during repetitive tasks. The compact stack stores neatly on the shaft in any order and stays accessible under load.

• Six flip sockets on a single, easy-grip shaft
• Quick rotation to the correct hex size without removing the shaft
• Order sockets on the shaft as you prefer for efficient workflow

Can I use these with an impact driver and will they hold up?

Yes — both the shafts and the flip sockets are rated for impact use, so they are built to handle high-torque applications that would damage standard nut drivers. Heat-treated components and robust geometries resist wear and deformation, maintaining grip and fit under repeated impact. Use them confidently with your impact or Klein quick-connect handle for heavy fastening tasks.

• Impact-rated shafts and sockets for high-torque compatibility
• Two 5-inch shafts included for reach and leverage
• Durable materials and construction for professional environments

What sizes are included and how does the 1/4" bit-holder work?

The set covers six common SAE and six common metric hex sizes so you rarely need additional nut drivers. A built-in 1/4" bit-holding feature accepts standard hex bits, expanding the kit to drive screws and specialty bits while remaining on the same shaft as the flip sockets. This dual-purpose capability reduces tool changes on the job.

• SAE sizes: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16"
• Metric sizes: 7mm, 8mm, 10mm, 12mm, 13mm, 14mm
• 1/4" bit holder fits common hex driver bits for added versatility

How does storage and organization work with this kit?

The flip sockets slide onto the shaft and can be arranged in any sequence, keeping sizes together and reducing the chance of losing individual drivers. The compact footprint saves space in a pouch or toolbox while providing immediate access to multiple sizes. Because everything mounts to the shaft, it's quicker to carry and deploy than a tray of separate nut drivers.

• Flip sockets store directly on the shaft for compact organization
• Customizable ordering allows ergonomic placement of frequently used sizes
• Compact kit footprint fits into tool bags and small drawers

Who is this for? The Klein Tools 32933KIT is made for electricians, HVAC technicians, contractors, and maintenance professionals who need a rugged, space-saving solution for switching between SAE and metric hex fasteners. It also benefits tradespeople who favor impact tools and require reliable, long-lasting driver components on the jobsite. If you want fewer tool changes, impact compatibility, and a compact system that keeps multiple sizes at hand, this kit is designed to meet those needs.
