Cleaning out a cabinet today and came across these. 1/2-20 to 7/16-20. And 9/16-20 to 7/16-20. One right hand and one left hand threads.

I have remembered what they are! And will be throwing them in the recycle pile. But I’ll hold out to see if anyone knows!

I'm thinking the same as alfadan. They look like the adapters for my riv-nut setter.

They are solid no thru holes.
