Klein Tools 32933KIT Impact-Rated Socket Set, SAE and Metric, 12 Sizes

Where it shines

For jobs that call for both SAE and metric fastener sizes, the Klein Tools 32933KIT combines a range of nut-driver sizes in a compact set. Its six flip sockets provide 12 hex sizes, and the 1/4-inch bit holder adds a way to drive screwdriver bits. That can suit someone who wants a versatile carry kit, someone working with only one fastener standard may prefer a more focused set.

The sockets and shafts are impact-rated and connect to an impact driver. A practical use would be switching between common hex fasteners during a repair without carrying a separate driver for every size. You’ll appreciate it if having both measurement systems in one set matters more than keeping a single-purpose kit. The sockets can be stored on the shaft in any order or orientation, and the sizes are color-coded for identification.

Quick overview

• Type: SAE and metric impact-rated flip socket set
• Sizes: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 7mm, 8mm, 10mm, 12mm, 13mm, and 14mm
• Included components: Six flip sockets, two 5-inch impact-rated shafts, and a 1/4-inch bit-holding feature
• Material and finish: Alloy steel with a manganese phosphate finish
• Connection: Quick-connect hex shaft for an impact driver or a Klein quick-connect handle

The included sizes cover a mix of frequently used SAE and metric hex fasteners, while the bit-holding feature gives the 1/4-inch socket an additional role. The manufacturer describes the socket depth as shallow and optimized for hex-head fasteners, so the set is specifically oriented toward that kind of fastening rather than being a general-purpose deep-socket assortment.

Customers describe the set as versatile and useful for carrying fewer separate tools, and some note compatibility with other driver handles. Feedback on the design is mixed, so that aspect may come down to personal preference rather than being a clear point in its favor.

Who it’s for

This set makes sense for users who regularly move between SAE and metric hex sizes and want sockets that can connect to an impact driver. It also suits a compact tool-carry approach: the flip sockets combine multiple sizes, and the set includes a bit-holding function. If your work is limited to one size system, a dedicated set may be a simpler fit.

It might not be a great match if you need a handle included, the quick-connect handles are not part of the set. The shallow socket depth is another relevant detail if your fasteners require deeper reach. Those are specific trade-offs to weigh against the convenience of having both SAE and metric sizes together.

Before you decide

Which sizes are included? The set covers six SAE sizes from 1/4" to 9/16" and six metric sizes from 7mm to 14mm, as listed above.

Can it connect to an impact driver? Yes. The quick-connect hex shaft attaches to an impact driver, and the sockets and shafts are described as impact-rated.

Does it include a handle? No. It is designed to work with an impact driver or a Klein 1/4-inch quick-connect handle, but the handle is not included.

Buying verdict

The 32933KIT is worth considering when one kit needs to cover both SAE and metric hex fasteners, with impact-driver compatibility and a bit-holding option. Its strongest practical advantage is the range of sizes in six flip sockets, rather than specialized reach or a supplied manual handle. Choose it for mixed-size work and compact carrying, look elsewhere if you need deep sockets or want a handle in the box.
