Carlyle 3/8 Drive 21mm 6 Point Chrome Socket (CS38021M)

Description

Genuine Carlyle · Part no. CS38021M

Here is a 21mm socket, 6-point and standard length, for 3/8in drive tools. It is about the largest size that makes sense on a 3/8in ratchet, useful for a 21mm head in a cramped spot where a bulkier 1/2in drive setup will not fit, rather than for fixings that are done up hard.

Good to know

• Can I use it on 21mm wheel nuts? It fits the head, but wheel nuts are tight and safety-critical: break them loose with 1/2in drive and a long bar, and tighten with a torque wrench to the maker's figure.
• Why 6-point rather than 12-point? The six flats grip the faces of the hex, not the corners, so it is less likely to slip on a tight or slightly worn head.
• Will it go on an impact gun? No, this is a chrome socket for hand tools only.

Which one?
