The description states that this socket has an overall length of 85mm, so ideal when you need a bit more length for longer screws or even screws that are difficult to reach. ” but the inner plastic part makes the effective socket depth only 11 mm (less than 1/2 inch). That means it hooks about half the length of my lug nuts. Otherwise it looks well made, but the shallow effective depth on a long base is impractical. I'll bring this back and look for something similar but deeper.
