Hex, or Allen screwdrivers are for screwing and unscrewing Allen head screws.
Flat head screwdrivers were the original screwdriver, possibly being invented around 1460. They were the only type of screwdriver until the early 20th century.

There are more than two types, but the main categories are flat head and cross/star screwdrivers. Actually, there are four: flathead or standard, phillips head, hex or Allen head, or Torx or star head. Torx/star head and Allen/hex head fasters are more often than not bolts, differentiated from screws, but there are a number of different styles of actual screws that are manufactured for these two bits as well.
