These are parts to stack IKEA LACK tables on top of eachother. Two IKEA LACK tables make for a great printer enclosure.
I don't have specs on the screws, but they are countersunk wood screws. The head can be max 9mm wide and 4mm tall at an angle of 45 degrees. The screw thread itself can be ~4mm max.
There are a few others who made feet like these but they didn't really suit me. These are fastened with a single countersunk screw that is hidden underneath the legs of the table.
Edit: I've added feet for under the legs of the bottom table.
