What's the difference between waterproof screws and wire drawing rods?

A water stop is welded in the middle of the waterproof screw. After the concrete wall is poured, the water stop and concrete become a whole, which can achieve waterproof effect.

The wire drawing rod is a threaded screw, which is combined with aluminum film shell when used. After the wall is poured, the drawing rod can be reused, but it can't stop the water.
