A hitch pin consists of a small metal rod that prevents certain trailer hitch parts such as the ball mount shank from slipping out of the hitch receiver tube. Bent hitch pins are often in an “L” shape. The hitch pin is designed for insertion into the side of the hitch receiver. It is moved through the ball mount shank all the way to the other side. The hitch pin shear strength is a key factor in its successful function. A hole is present on the end of a safety lock hitch pin, which is designed to receive a clip made from spring steel and shaped like a hairpin. This hitch clips ensure the pin remains in the receiver.
