ASME B30.10 specifies that markings on a hook must be applied to which surface?

Explanation:
Markings on a hook must be placed on a surface that won’t wear away in service. This keeps important information like capacity and manufacturer legible throughout the hook’s life, which is essential for safe lifting. Surfaces such as the throat, inside the curve, or the top edge are routinely contacted, abraded, or impacted during use, so markings there would wear off quickly and could lead to unsafe or noncompliant use. Placing the markings on the non-wearing area avoids that problem, ensuring the identification information remains readable over time.
