Which of the following is NOT a purpose of the small screw pin clevis?

• A. As a tie down point
• B. As a lifting mechanism
• C. As a flotation device
• D. As an attachment point

Answer: (C)

The small screw pin clevis serves various essential functions in lifting and securing equipment, but it is not designed to act as a flotation device. It typically functions as an attachment point for connecting components in rigging and lifting operations. When utilized correctly, it provides a reliable means for securing loads to ensure they can be safely lifted or tied down.

Specifically, its roles include serving as a tie-down point, which is critical for stabilizing loads during transport, and functioning as a lifting mechanism by connecting a load to a hoisting system. However, flotation devices are intended to aid in buoyancy and support weight in water, which is outside the capabilities and intended use of a screw pin clevis. Thus, option C correctly identifies a purpose that does not align with the design and functionality of a small screw pin clevis.
