Linchpin

 

a wedge-shaped rod that fits into a hole in a part and prevents another part from shifting to one side while fastened to the first part. The shape of a linchpin prevents the pin from falling out of the hole. Linchpins were used in horse-drawn vehicles to prevent the wheels from coming off the axle. They are used for unstrained joints between parts, for example, as safety pins in hand grenades.
