What is the primary application for an AN clevis bolt in aircraft construction?

In aircraft construction, the primary application for an AN clevis bolt is for shear load applications. This type of bolt is designed with a notch that allows it to connect components in a manner that effectively transfers loads within the structure. Specifically, clevis bolts are often used in conjunction with a clevis, which is a U-shaped component that supports hinges or other connecting parts where shear strength is crucial.

When these bolts are used, the load applied is typically perpendicular to the axis of the bolt, making them ideal for shear conditions rather than tension. These applications can be found in various parts of an aircraft, such as in control surface connections or attachment points for structural members, where forces act primarily in a shear direction rather than pulling or tensioning the components apart.

In contrast, tension load applications would require fasteners capable of withstanding pulling forces, such as bolts and screws specifically rated for tension, which is not the primary function of clevis bolts. Similarly, while clevis bolts can provide structural support, they are specifically optimized for shear loads rather than broader structural support roles that might require different types of fasteners. Therefore, the focus on shear load applications correctly identifies the typical use of AN clevis bolts in aircraft construction.
