What differences are there between through bolts and concrete screws?

Versus

Both are suitable for medium-weight and heavy fixings in concrete, solid brick and natural stone. The long thread of a through bolt (S-KA+, S-KAK+, S-KAH+) is suited for distance installations in which the object to be fastened is away from the base. In large sizes (≥ M12), through bolts are easier to install and the product range is more extensive. Moreover, a through bolt allows a minor deflection in installation and is therefore better suited for reinforced concrete.

A concrete screw (S-CSA) is quick to install and easy to remove, so it is an excellent choice for temporary installations, such as formwork. The reusability of screws saves money. A concrete screw is suited for fixings requiring small edge distances and spacings in columns and outer corners, for example.
