- Manufacturer’s Identification: Typically includes the company name or logo.
- Material Grade: Indicates the type of steel used in the hook.
- Heat Treatment: Specifies the heat treatment process applied to the hook.
- Size and Dimensions: Provides details about the hook’s physical characteristics.
