It's a socket!,
Verified Purchase(What is this?)
This review is from: Faithfull SOC1221 21mm Hexagon Socket Chrome Vanadium 1/2-inch Drive (DIY & Tools)
Not much to say really. I had already gotten a smaller 19mm Faithfull socket for a Breakers-bar, and subjected it to pretty heavy loading - and it's still working! So I decided to stick with the Faithfull brand.
