I'm clueless on what these are... Any ideas?
Nifty little quick nuts to place on the nuts on top of the block at the corners when you are under the car removing block to pans bolts.....nice set!
That way you can remove block to pan bolts with only one hand and one wrench.
Aka: Nut holders. I think someone posted similar ones before.

Around here we call them a "third hand" socket.
