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.

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.
