What is the function of an “open clevis” in sheet metal structures?

The function of an “open clevis” in sheet metal structures is to allow for attachment while accommodating movement. This type of clevis is designed to create a connection that can pivot or slide, enabling components to move relative to each other without being rigidly fixed in place. Such flexibility is essential in applications where parts must work together while still permitting some degree of movement due to thermal expansion, vibrations, or mechanical dynamics.

In contrast, other options either describe functions that do not apply to an open clevis or represent characteristics of different fasteners. For instance, while providing a rigid connection is important in many systems, this is not a function served by an open clevis. The prevention of corrosion also does not pertain specifically to the clevis itself but rather to the materials and coatings used in assembly. Strengthening joints typically involves different structure designs or reinforcements rather than utilizing an open clevis, which is inherently designed to provide mobility.
