Ko-Ken KO2127-8 Nut Twister Socket, 8 mm, 1/4 in Drive

The Ko-Ken 2127 Nut Twister socket is made in 7 sizes from 4 to 10 mm, each with a 1/4 in drive.

The catalogue says the sharp edges of the Nut Twister socket opening tighten around the nut, bolt or stud and turn it off, so it can be used to remove rounded-off nuts, bolts and studs (manufacturer-stated).

The 1/4 in drive comes from the store listing; the catalogue page prints the 2127 sizes but not a drive size, and it does not say whether the sockets are for hand or impact use.

Each size is listed in the table below with its length and weight.
