Pins and feather keys play a central role in connection technology and are fundamental mechanical connecting elements that are used in numerous applications for secure force transmission and positioning. Pins and keys are particularly important in the mechanical engineering industry.
Pins are cylindrical or cone-shaped pieces of metal that are placed in bores or through holes to connect parts together. Their versatility ranges from simple alignment pins to highly specialized threaded pins. These pins are not only used to fix components, but also enable the smooth transmission of torque.
Keys, on the other hand, are narrow, flat pieces of metal that are inserted into specially manufactured tongue and groove systems. Their main purpose is to transmit torque between the shaft and hub, creating a positive connection. The precise fit of the groove and key ensures precise alignment of the components and prevents axial displacement.
