Klein Tools 66011 – Frequently Asked Questions
1) How does the Klein 2-in-1 impact socket switch between the two sizes?
You flip between sizes hands-free. The Klein 66000-series 2-in-1 impact socket is single-ended with two coaxial spring-loaded hex sockets stacked in one body, so pushing the socket onto the next fastener size engages that size without pulling an insert or swapping tools. A cross hole design keeps the adapter and socket from separating unintentionally, and the socket is color coded so you can pick the size off the belt.
2) Which size pairs does the Klein 2-in-1 impact socket come in?
Five pairings cover the common electrical and structural fastener sizes: 1/2 and 3/8-inch (Cat. No. 66011), 5/8 and 7/16-inch (66012), 7/8 and 11/16-inch (66014), 1 and 13/16-inch (66015), and 1-1/8 and 15/16-inch (66016). Each is a single tool holding both sizes, so a crew covering 3/8 through 1-1/8 inch needs all five rather than one adjustable unit.
3) Will the Klein 2-in-1 impact socket fit my 1/2-inch impact wrench?
Yes. The drive is 1/2-inch square, so it mounts on any 1/2-inch drive impact wrench or driver, including Klein's own BAT20CW and BAT20CW1 compact impact wrenches. It is impact rated, not a chrome hand socket, so it is built for the hammer action of a driver. If your tool is 3/8-inch drive you would need a step-up adapter, which is not included.
4) How deep is the Klein 2-in-1 impact socket, and will it reach a nut on a long threaded rod?
It is a deep socket measuring 3.1 inches on the depth axis, with a 0.87 inch height and width. That depth clears protruding thread on strut nuts, anchor bolts, and threaded rod that a standard-length socket bottoms out on. On very long rod stickout you will still need an extension or a rod coupling nut driver instead.
5) What is the Klein 2-in-1 impact socket made of, and does it meet a socket standard?
Body material is 4140 chrome-moly steel, the alloy normally specified for impact-driven sockets because it deforms rather than shatters under hammer loading. The socket is built to ASME B107.2, the dimensional and performance standard for hand and impact socket wrenches, which matters if your spec sheet or MRO purchasing requires a standards-compliant tool.
6) I'm buying for an electrical crew. Which two of these sockets cover the most day-to-day work?
For strut, hanger, and panel work the 1/2 and 3/8-inch tool (Cat. No. 66011) plus the 5/8 and 7/16-inch tool (66012) cover most channel nuts, machine bolts, and lag hardware. Step up to 7/8 and 11/16-inch (66014) or larger for switchgear, transformer pads, and structural anchors. Each socket carries two sizes, so two tools replace four conventional sockets in the pouch and each is color coded for quick size identification.
