7318.15.80.66 - Cap screws 🖩

This HTS category, 7318.15.80.66, specifically covers cap screws of iron or steel. Cap screws are characterized by their headless design, typically featuring a drive socket (such as hexagonal or Torx) on their top surface. They are primarily used for applications where a protruding head would be undesirable or where a cleaner aesthetic is required, and they often function as set screws or machine screws.

This category is distinguished from its sibling, 7318.15.80.69 (Other), by the specific form factor of a "cap screw" with its integrated drive mechanism. While both fall under the broader classification of "Other screws and bolts, whether or not with their nuts or washers," with shanks or threads of 6 mm or more and hexagonal heads, 7318.15.80.66 targets those with a recessed or internal drive that defines them as cap screws.

As this is a leaf node, there are no further subcategories. The classification is finalized at this level based on the article being a cap screw of iron or steel, with a hexagonal head, and meeting the diameter and other criteria of its parent categories. Importers should verify the physical characteristics of their articles to ensure they meet the definition of a cap screw to correctly classify under this code.
