7318.12.00.00 - Other wood screws

This HTS category, 7318.12.00.00, specifically covers "Other wood screws" made of iron or steel. These are threaded fasteners designed for joining wood to wood, or wood to other materials, characterized by their coarse threads and often a pointed tip to facilitate insertion into wood. Unlike coach screws (7318.11.00.00), which are typically heavier and have a hexagonal head for driving with a wrench, wood screws generally feature different head types such as slotted, Phillips, or Torx for screwdriver engagement.

The distinction from other categories within 7318.15 (Other screws and bolts) lies in the specific design for wood applications. While general screws and bolts may have finer threads or be intended for use with nuts and washers in broader construction or mechanical assemblies, wood screws are optimized for penetration and holding power within wooden substrates. This category serves as a distinct classification for these specialized fasteners.

As a leaf node, 7318.12.00.00 does not have further subcategories. Therefore, the focus remains on precisely identifying articles that meet the criteria of a wood screw, excluding those specifically classified under other sibling headings, such as coach screws or screw hooks. Classification within this heading hinges on the screw's design, thread type, and intended primary application in woodworking.
