ASME B30.10 markings shall be forged, cast or die stamped on what area of the hook?

• A. Throat area
• B. Non-wearing
• C. Body of hook
• D. Heel area

Answer: (B)

The main idea is that markings on a hook must stay legible throughout use. ASME B30.10 requires that the identification marks—like working load limit, size, and manufacturer—be forged, cast, or die stamped into the hook in a place that will not wear away during normal operation. Putting markings on a non-wearing area ensures they remain readable even after contact, abrasion, and repeated loading. The throat area is where the load travels and surfaces experience wear, while the body and heel can also be exposed to abrasion or deformation; markings in these regions are more likely to fade or become illegible. By placing the marks on a non-wearing area, the information stays intact, supporting safe operation and traceability.
