7616.10.70 - Having shanks, threads or holes over 6 mm in diameter

This HTS category, 7616.10.70, encompasses aluminum articles that are similar in function to fasteners but are specifically characterized by having shanks, threads, or holes exceeding 6 mm in diameter. This includes a range of aluminum components designed for joining or structural purposes where the larger dimension is a key distinguishing feature. Examples might include specialized bolts, larger gauge rivets, or custom-made threaded components where the substantial diameter indicates a heavy-duty application.

Distinction from its sibling category, 7616.10.90, which is "Other," lies in the explicit diameter criteria. While 7616.10.90 would cover a broad spectrum of miscellaneous aluminum articles not otherwise specified, 7616.10.70 is narrowly defined by the 6 mm threshold, focusing on components with a more significant physical presence or intended for applications requiring greater strength or fastening capacity.

This category is further subdivided to refine classification based on specific functional types. The subcategory 7616.10.70.30, "Threaded fasteners," specifically isolates those aluminum articles that are designed for screw-thread engagement, ensuring they are distinct from other large-diameter aluminum components. The remaining items within this large-diameter group fall under 7616.10.70.90, "Other," providing a residual classification for qualifying aluminum articles that do not fit the more specific "threaded fasteners" designation.
