What are lifting lugs used for?

Rigging materials used to clamp onto surfaces such as shell plates or sheet metal Decorative handles Fastening hardware for bolts Tools used for cutting sheet metal

Correct Answer:

Rigging materials used to clamp onto surfaces such as shell plates or sheet metal

Explanation:

Lifting lugs provide a dedicated, rated point to attach rigging for hoisting. They are attached to a workpiece—often welded or bolted onto surfaces like shell plates or sheet metal—to give slings, shackles, or chains a secure place to grab and lift the part safely. This makes the lifting process controlled and reduces the risk of damage or failure during hoisting. The other options describe items that serve entirely different purposes—decorative handles, general fastening hardware for bolts, or tools for cutting sheet metal—so they don’t match the role of a lifting point used in rigging.
