What is the primary use of mechanical fingers?

• A. To hold or retrieve items out of normal reach.
• B. To measure torque on fasteners.
• C. To mark starting holes in metal.
• D. To monitor cylinder pressure.

Answer: (A)

Mechanical fingers act as a gripper that reaches into tight spaces to grab and move parts. Their main job is to hold or retrieve items that aren’t easily reachable by hand, such as a fastener or a tool dropped behind an obstruction, without needing to disassemble or stretch awkwardly. They are designed to provide a secure, delicate grip and can be driven by air, springs, or mechanical linkages to reach into confined areas and pull the object out or place it where you can access it. They aren’t used to measure torque, mark starting holes, or monitor cylinder pressure, which require different tools and functions.
