Description

Genuine Carlyle · Part no. CIS3821M

This is a standard-length 21mm impact socket with a 3/8in square drive and a 6-point opening, made from chrome molybdenum steel. The short body keeps a compact impact wrench close to the work on a 21mm head where there is not much room above it.

Good to know

Will it fit a 1/2in impact wrench? Only with a 1/2in female to 3/8in male impact reducer between them, and remember the smaller socket is then the weak link.
Can I tighten wheel nuts with it? Use the gun only to run them on, then finish with a torque wrench to the vehicle maker's figure and recheck after a short drive.
Will the thicker wall get in the way? Possibly. Impact sockets are bulkier than chrome ones, so check the clearance around the head.

Which one?

To reach a 21mm nut on a long stud, the Carlyle 3/8 Drive 21mm 6 Point Deep Impact Socket (CISD38021M); to run this one from a 1/2in gun, the Carlyle 1/2 Female -3/8DR Male Impact Reducer (CIADP1238).
