Copper; screws, bolts and nuts, threaded

HS v2022 Code: 741533

About copper; screws, bolts and nuts, threaded

HS code 741533 covers the trade and production of copper screws, bolts, and nuts. This industry plays a crucial role in the broader metal manufacturing and construction sectors, providing essential fastening components for a wide range of applications. As a key part of the global supply chain, the copper threaded fasteners industry contributes significantly to the overall health and growth of the international economy.

Production process

The production of copper screws, bolts, and nuts typically involves a multi-step process. First, raw copper is melted and cast into the desired shapes and sizes. The cast pieces are then subjected to various metalworking techniques, such as threading, cutting, and finishing, to create the final threaded fasteners. Advanced manufacturing methods, including computer numerical control (CNC) machining and automated assembly lines, help ensure consistent quality and efficiency in the production process.

Production inputs

The main inputs required for the copper threaded fasteners industry include raw copper, as well as various tools and machinery necessary for the metalworking and finishing processes. Copper is the primary raw material, sourced from 740100 Copper, unwrought mines and smelters around the world. Additionally, the industry relies on specialized equipment, such as lathes, threading machines, and polishing tools, to transform the raw copper into the finished products.

Production outputs

The primary outputs of the copper threaded fasteners industry are the various types of screws, bolts, and nuts that are used in a wide range of applications. These copper fasteners are often used in the construction, automotive, and machinery industries, where they are essential for securing and joining components. Other industries that may consume the output of this industry include 731815 Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers and similar articles, of iron or steel, not threaded, 732690 Other articles of iron or steel and 732619 Other cast articles of iron or steel.
