Which statement best describes the difference between a cotter pin and a clevis pin?

The distinction between a cotter pin and a clevis pin lies primarily in their respective functions within mechanical assemblies. A clevis pin is used to secure two components together, acting as a pivot point or a hinge. It often features a groove or hole that allows a cotter pin to be inserted into the end of the clevis pin to prevent it from coming loose or becoming dislodged. This securing action is essential in applications where stability and safety are critical, such as in various machinery and equipment.

On the other hand, the cotter pin does not function to hold two parts together directly; rather, it complements the clevis pin by securing it in place. Therefore, the statement accurately reflects that the clevis pin serves a specific purpose in the assembly, while the cotter pin serves to maintain the integrity of that connection. Understanding this relationship is crucial for recognizing their unique roles in fastening and securing mechanical systems.
