What is an eye bolt used for in rigging?

• A. A threaded anchor point used to attach rigging hardware or lines.
• B. A sensor that stops movement at a preset position.
• C. A metal plate used to distribute a load across multiple points and prevent hardware deformation.
• D. A boundary to keep people away from hazards.

Answer: (A)

The main idea here is that an eye bolt serves as a threaded anchor point for rigging hardware or lines. It’s a fastener with a loop (the eye) that screws into a structure, providing a secure place to attach rope, wire, cables, shackles, or hooks. In rigging, you rely on that fixed point to transmit load from the line to the structure, so the load direction should be along the bolt’s axis and the eye bolt must be rated for the force involved. Side loading or bending the eye can cause failure, so proper installation and matching the correct size and rating are essential.

The other options describe different components with unrelated roles: a sensor that stops movement, a plate that distributes load, or a boundary to keep people away. Those aren’t anchor points for rigging.
