You might check the NDS. Section 11.3 provides design information for Lateral design of wood screws in single shear (wood to wood). NDS also provides capacities where lag screws are used in place of wood screws. I believe that a 1/4" lag screw would provide almost twice the lateral capacity of a 16d nail depending upon depth of embeddment and the species of wood you are connecting. Another source with possibly more tables to use would be the AITC (American Institute of Timber construction) manual. I remember at least one table for different gauge screws and the lateral capacity by specific gravity of the wood material. You also might contact suppliers such as Hilti who provies documentation for the screws used in their automated screw guns. I'm sure others on this list can be of more direct help.
