I'm not sure if that's the best usage of your screws, since the type 94 will convert to type 3 depth charge. The ASW stat of t3 depth charge is still lower than a type 3 sonar (+8 to +10), and you can get the sonar via crafting using very few resources each try. I would recommend using your screws to upgrade more important items such as guns and planes.
