The hex screwdriver is used for internal wrenching and which type of screws?

Explanation:
Hex screwdrivers engage screws that have a hexagonal recess inside the head, known as an internal drive or Allen drive. This setup is most typical for set screws, which are designed to be tightened with an Allen key to secure parts in place, such as a shaft in a collar or inside a bore. Wood screws use external slots like a screwdriver slot, while self-tapping screws and many machine screws can have various drives, but they aren’t defined by an internal hex drive in the same common way as set screws.
