Overview
This category encompasses structural bolts of iron or steel that are intended for use in construction and infrastructure projects. These bolts are characterized by their robust design and are specifically engineered to withstand significant stress and load-bearing requirements in structural assemblies. They typically feature a substantial shank and threaded portion, designed for secure fastening in applications such as connecting steel beams, girders, and other load-bearing components.
Distinguished from its sibling, "Track bolts" (7318.15.20.20), which are specifically designed for railway applications, this category focuses on bolts used in a broader range of construction contexts. Unlike "Bent bolts" or "Other" bolts at this level, structural bolts are defined by their intended application and inherent strength for static load-bearing in building and engineering structures, rather than their form or a general "other" classification. The key classification criteria revolve around the bolt's purpose in structural assembly and its manufacturing specifications to meet construction industry standards.
As this is a leaf node, there are no further subcategories to explore. Therefore, the focus remains on accurately identifying bolts based on their structural application. This includes considering factors such as head type (e.g., hex head, heavy hex head), thread length, material specifications (e.g., high-strength steel alloys), and any relevant certifications or standards (e.g., ASTM, SAE) that confirm their suitability for structural purposes. Importers and exporters should carefully review product specifications and intended use to ensure correct classification under this specific heading.
