O2 Oxygen Sensor Socket 3/8-Inch Drive x 7/8-Inch (22mm)

Great tool for the job

The quality of the tool was impressive and got the job done in no time compared to the struggles I had with other tools. Quick delivery also.

7/8" = 22.225mm. This is a 7/8" wrench, so it's a bit sloppy on 22mm. I plan to use it in a couple of days to remove a 22mm O2 sensor... hopefully, it won't round off the hex corners.

There are some cheap ones that don’t work because you can’t insert a ratchet onto the tool. This one is a keeper, the bad one was a different brand and seller.

well builted,much better than the longer version that is knowned to slip.
