The idea is that you're supposed to put them on the wrench drive square
before you snap on a socket or extender bar. The disks are larger than
the wrench heads so you can "spin" the socket with your fingertips.

I think I've had them for about 30 years and I can't recall ever using
one of them.

I have 3/8". Never used it.

But one day I might. I had a 67 Catalina with a 400 cid engine and I
couldn't get anything in to change the number 1 sparkplug, not even
the socket alone. I'm sure they made a socket for this purpose. I
just didn't have it. (I ended up removing the big cast iron AC
bracket and taking it to a shop to get a a piece cut out of it. to get
access to the plug.

I had a '69 Charger w/ "only" the 383 and #8 on it was only accessible
w/ a "shorty" plug socket w/ the hex on the rear for a tappet-wrench
thin open-end wrench to turn about 1/32 of a revolution per
try...until I learned the "trick".

Shop foreman told me -- you set a jack under the flywheelhousing and
jack a couple of strokes -- then there's sufficient clearance for a
wobblehead...

This old guy and worked pits for "The King" in his earliest days w/
Mopar and was basically the font of all knowledge Mopar-related...
