Bolts can be used for fastening connections and are applicable in fields such as machinery manufacturing, aerospace, highway transportation, and electric power energy. This dataset includes main raw and auxiliary materials, energy, and waste from the production process; infrastructure such as production equipment and factory construction are not included within the system boundary of the dataset. The life cycle inventory is compiled from data derived from multiple sources. The bolt manufacturing process includes stages such as raw material preparation, cutting and drilling, tapping and thread rolling, heat treatment, surface treatment, and inspection.
