Klein Tools 32933 Impact Flip Socket Set: Six SAE Sizes on One 5-Inch Shaft

Three hex-head sizes can turn a short fastening job into repeated trips back to the socket case. The Klein Tools 32933 keeps six SAE nut-driver sizes on one 5-inch impact-rated shaft, using three reversible flip sockets that stay on the tool while the required size changes.

This article covers the exact four-piece 32933 set: one shaft plus three SAE flip sockets in 1/4, 5/16, 3/8, 7/16, 1/2 and 9/16 inch. It is not the metric 32933M, the larger SAE/metric 32933KIT, the 32910 package with a hand handle or the older 32907 configuration. An impact driver or compatible 1/4-inch quick-connect handle is not included.

Three flip sockets put six SAE sizes on the shaft

Each socket has a usable hex size at both ends. Turning a socket around changes the working size, so three pieces cover six common SAE hex heads without six separate sockets. Klein color-codes the sizes and says the sockets can be stored on the shaft in any order or orientation. The markings and color bands make a needed size easier to identify before the trigger is pulled.

The working set stays together instead of spreading loose sockets across a pouch or ladder tray, especially when a task alternates among the included sizes. The benefit stops at those six SAE dimensions; metric fasteners, larger nuts and uncommon profiles still need the correct separate socket. Color helps identification but does not replace checking the marked size and fit.

The 5-inch shaft reaches while every part remains impact-rated

Klein lists the overall shaft assembly at 5 inches and says every component is impact-rated. The 1/4-inch quick-connect end attaches to an impact driver or Klein quick-connect handle, letting the same socket stack move between powered and compatible manual driving without changing to a different set. The long shaft also places the driver body farther from the fastener than a short adapter would.

One compact assembly combines reach, six socket fits and impact compatibility, but length does not create universal access. A recess, obstruction or long stud can still require an extension or deep socket. Klein describes these sockets as shallow and optimized for hex-head fasteners, so do not treat them as deep sockets for nuts traveling far down threaded rod.

The 1/4-inch end also holds bits and a magnet retains fasteners

The 1/4-inch socket has a second role: Klein says its design can drive 1/4-inch hex fasteners and hold screwdriver bits. A rare-earth magnet retains bits and hex-head fasteners, which can help keep a fastener at the working end when the supporting hand is occupied. This adds a seventh function without adding another sleeve to the shaft.

The phrase “bit holding” matters. The set does not become a complete screwdriver-bit kit, and the product contents list only the shaft and three flip sockets. Bring the correct impact-rated bit for the screw profile and load involved. Magnetic retention helps position hardware, but it does not verify size, keep a tilted socket square or prevent cross-threading. Start the fastener carefully before applying impact force.

Buy it for repeated SAE hex-head changes

Choose the 32933 when six common SAE hex sizes recur in impact-driving work and keeping them on one shaft would reduce socket changes or misplaced pieces. Its reversible layout is easy to inspect, and the color bands make the current size visible while the unused sockets remain stored behind it.

Skip it when the job is mainly metric, needs deep sockets, requires a full ratchet set or must be performed on energized equipment. Klein explicitly says never to use the tool on or near live electrical circuits, states that it is not insulated and will not protect against electrical shock, and warns against prying or chiseling. Approved eye protection is also part of the manufacturer’s instructions.

The Klein Tools 32933 is persuasive because the compactness comes from a clear mechanical arrangement rather than an inflated piece count: three reversible sockets, six named SAE sizes, a bit-holding 1/4-inch end and one impact-rated shaft. For the right hex-head work, that can replace repeated case searches. Outside those sizes and shallow-socket conditions, the dedicated socket remains the safer and more accurate choice.

### Verdict

Buy the Klein Tools 32933 when 1/4- through 9/16-inch SAE hex heads repeatedly share the same impact-driving task. Choose metric, deep or insulated tooling when the fastener or work environment requires it.
