Ordinary flat keys have good centering, high positioning accuracy, and are easy to assemble. However, they cannot achieve axial fixation of parts on the shaft and are used for shafts that are high-speed or subjected to impact or variable loads; Thin flat keys are used for thin-walled structures and places with low torque transmission; The directional flat key is fixed to the shaft with screws, used in situations where the parts on the shaft do not move much along the axis

Flat key is a key that relies on two sides as working surfaces and transmits torque through the compression between the key and the keyway side. Flat keys are divided into three types: regular flat keys, thin flat keys, and directional flat keys.
