How do you connect 2 pieces of wood using countersunk screws?

To connect two pieces of wood using countersunk screws, first, align the pieces where you want to join them. Drill a countersink hole in the top piece to accommodate the screw head, ensuring the hole is slightly larger than the screw diameter. Then, drill a pilot hole through both pieces to prevent splitting. Finally, insert the countersunk screw into the pilot hole, tightening it until the screw head is flush with the wood surface.
