Screwdrivers and Nozzle and drive sockets

Each screwdriver with nozzles has an interchangable head (bit) that is inserted into the bit driver. There are flexible nozzles that are used for working in hard-to-reach areas. The design of screwdrivers provides for both an elongated and a shortened rod, a T-shaped handle, a ratchet (ratchet) mechanism, etc. The end head is a working nozzle that provides maximum contact with fasteners and is used in locksmith work when repairing cars or various equipment.
