Drill hole size suggestion for this pass-through socket
The 0.043" region is the part that goes through the board, and then the 0.061" rim sits on top of the board.

Given that drill sizes tend to be metric, your 0.043" hole is 1.0922mm, so the next two metric sizes up would be 1.1mm or 1.2mm. Given that is the drill size and the holes will be plated, I would go for the larger of the two (1.2mm) to allow a tolerance for the drill sizes being smaller - though you can check your PCB manufacturers spec as they will usually tell you the hole tolerance.

In any case you want it to be narrower than 0.061" (1.54mm), so that means your drill hole should be no smaller than 1.1mm and no larger than 1.5mm.

The best advice is check what the manufacturing tolerance of your PCB manufacturer is and add this to 1.1mm to get your minimum size.
