These are metric sizes.
4.8mm is a mighty peculiar size - usually they go in for round numbers.  4.8mm is 0.19 inches.
ASME #10 screws are 0.19 inches diameter.

19mm is 3/4&quot;.  So they are 3/4&quot; long.
Any #10 x 3/4&quot; wood screw should do the trick.

By the way, 3.5mm is 0.138&quot; which is the diameter of ASME #6.
