When you disassemble something, where do you put the screws? It is possible that you will forget where you placed them, and lose them. To avoid this, you may have to prepare a separate case in which to store them during every job. IN HOLE DRIVER is a screwdriver with a hollowed-out handle that serves as a storage space. The user can temporarily deposit the screws in the case, and retrieve them easily during reassembly. A magnetic ring is concealed behind the storage case. It ensures that the metallic screws will be securely contained in the case. This is particularly useful when one is working on a stepladder.
