Which method would you NOT use to secure a clevis bolt?

In the context of securing a clevis bolt, the selected answer indicates that the use of a jam nut is not typically applicable. When securing a clevis bolt, the primary concern is to ensure that the bolt maintains its position and does not loosen due to vibration or other forces.

A clevis bolt is often used in conjunction with a clevis that allows for rotational movement; therefore, it is important for the securing method to accommodate this kind of application. A shear nut is designed to be tightened to a specified torque, providing security against loosening due to shear forces. A cotter pin serves as a very effective means of securing a clevis bolt by passing through a hole in the bolt, preventing it from rotating or coming loose. Lock washers can also be effective, as they create friction between the nut and the surface, helping to resist loosening from vibrations.

In contrast, a jam nut is typically used in scenarios that involve direct axial loading, where two nuts are tightened against one another to prevent loosening. However, due to the nature of clevis bolts, which usually operate in applications requiring rotation and flexion, a jam nut does not provide adequate security in this specific configuration. Therefore, it is not a preferred method for securing a
