Best Product – New Klein Tools 2-in-1 Impact Socket Set for Construction & Utility Pros

Klein Tools has introduced new 2-in-1 impact socket set (66010), with each socket fitting two different fastener sizes.

The new Klein Tools impact socket set features 6 tools that can fit 12 common fastener sizes used in construction and utility applications. They feature 12pt socket ends, with the inner size being spring-loaded for quick hands-free adjustments.

The new Klein 2-in-1 impact sockets are also color-coded, for quicker size retrieval.

When placed over a fastener corresponding to the larger size, the inner sleeve depresses into the tool, and returns to its position when the job is done.

Here are the socket sizes included in the new set:

• 1/2″ + 3/8″
• 5/8″ + 7/16″
• 3/4″ + 9/16″
• 7/8″ + 11/16″
• 1″ + 13/16″
• 1-1/8″ + 15/16″

The sockets also feature a cross-hole design, for better socket retention when used with an adapter or impact wrench with pin detent anvil.

Price: ~$198 for the set

First Thoughts

I would presume that Klein’s initial 2-in-1 socket offerings were popular, leading to the expansion of the line with this new set.

Klein Tools highlights the easy hands-free adjustment, and that you can switch sizes without having to take your gloves off. They do seem to be convenient.

Is there a downside to these 2-in-1 sockets?

Update: CJ and Taras make good points in the comments. Due to the design, the inner sizes have thicker side walls compared to single-size sockets, which could potentially pose clearance issues depending on the application.

Additional Klein Tools x-in-1 Sockets

Klein Tools actually introduced a pair of 2-in-1 impact sockets last year. Klein 66004 and 66001 are both 3/4″ and 9/16″ sockets, with the first being 6pt, and the second 12pt. They work in the same way as the newly announced set.

According to product listing imagery, Klein has updated the look of their existing standalone 2-in-1 impact socket size – at least the 12pt – with the new styling and color-coding.

There is also a 4-in-1 square impact socket, NRHD4, with 3/4″, 13/16″, 1″, and 1-1/8″ square sockets. It is shown here attached to its included 1/2″ square drive 7/16″ hex quick-change chuck adapter (NRHDA4).

Lastly, there is also a 3-in-1 impact socket, NRHD, which is double-ended rather than being spring-loaded.
