Help with this one

Huuummmm!!!

What u found , does indeed have the look !
but, as u can see the shank relates proportionally to the size of the pin & the size of the slot , as where Rick & Sami's boxes have only one size of square hole.

To be convinced, I'd have to see the items that filled those holes..

 

Also, the poster's drawers have through holes, so the shank must have been smaller than the rest of the item, or it would simply fall through.
