Description

Genuine Carlyle · Part no. CISD38021M

A deep 21mm impact socket for 3/8in drive impact wrenches and air tools. It is 6-point, made from chrome molybdenum steel, and long enough to get over a 21mm nut on a protruding stud. It also turns by hand on a ratchet or breaker bar when the gun is not to hand.

Good to know

Is a 3/8in impact gun right for a 21mm fixing? For moderate fixings, yes. Many 21mm nuts are wheel or suspension fixings done up hard, and those suit a 1/2in drive gun and socket better.
Why might it not fit where a chrome socket goes? Impact sockets have thicker walls, so a nut tucked against a casting or down a recess may leave too little room.
Does it need a retaining ring? On an impact gun it is wise: a pin and rubber ring through the cross-hole stop the socket working off the anvil.

Which one?

For a lower stack, the Carlyle 3/8 Drive 21mm 6 Point Standard Impact Socket (CIS3821M); for more reach on the gun, the Carlyle 3/8 Drive 125mm Impact Extension (CIEXT3805).
