Ko-Ken KO4128L120M21 Nut Twister Socket, Long Type, 21 mm, 1/2 in Drive

The Ko-Ken 4128-120 is a long-type Nut Twister socket in 21 mm, 120 mm long (manufacturer-stated). It has a 1/2 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 1/2 in drive comes from the store listing; the catalogue page prints the long-type rows (17, 19, 21 and 22 mm) but not a drive size, and it does not say whether the socket is for hand or impact use.

Where this product is used

• Removing rounded-off nuts, bolts and studs
• Repair and maintenance work on machinery and vehicles
• Workshop work where a longer socket is needed

Features

• 21 mm size
• 120 mm long (manufacturer-stated)

Key specifications

Selecting the right option

Choose this socket when the 21 mm nut, bolt or stud you need to remove is recessed or needs extra reach. The catalogue does not say whether this series is for hand or impact use, so check before using it with a power tool.
