How is a clevis bolt used with a fork-end cable terminal secured?

A clevis bolt is a type of fastener specifically designed to work with a clevis or fork-end terminal to create a secure connection. The correct method for securing a clevis bolt is by using a shear nut tightened to a snug fit.

A shear nut has a unique design that allows it to be used effectively with clevis bolts, especially in applications where high shear forces are involved. The snug fit ensures that the connection can handle the operational loads without loosening over time, promoting reliability in mechanical systems. The use of a shear nut takes advantage of the specific geometric properties that provide resistance to rotation and prevent the nut from backing off, which is crucial in maintaining safety and functionality in mechanical assemblies.

In contrast, while other methods may provide some form of securing, they do not offer the same level of effectiveness or appropriateness for clevis applications as a shear nut does. For instance, lock washers and hex nuts are commonly used, but they do not provide the same level of shear resistance specifically needed for clevis configurations. Similarly, a flat washer under the bolt head is not sufficient alone to maintain the integrity of the connection, and relying solely on a cotter pin does not ensure a snug fit that resists movement under load.
