Product Description

Product Description

Carbon steel coated black double head bolts are cylindrical fasteners with threads on both ends, widely used in various industrial fields such as power, chemical, refining, valves, railways, bridges, steel structures, automotive and motorcycle parts, machinery, boiler steel structures, cranes, large-span steel structures, and large buildings. The characteristic of this type of bolt is that it has threads on both ends and a smooth rod in the middle, which is suitable for connecting thick plates or large equipment, as well as for use in places where ordinary bolts cannot achieve connection.
characteristic
1. Structural design: The design of the threads on both ends makes the connection more stable, without the need for additional nuts, simplifying the installation process.
2. Wide applicability: Suitable for connecting various metal components, such as steel, cast iron, and aluminum alloy components.
3. Surface treatment: Surface treatment is usually required, such as electroplating, blackening, oxidation, phosphating, etc., to improve corrosion resistance and ensure interchangeability of threads.
purpose
1. Large equipment connection: used to connect accessories on large equipment, such as mirrors, mechanical seal seats, gearbox frames, etc.
2. Thick plate connection * is suitable for situations where the connecting body thickness is large and the bolt length is long.
3. Special connection requirements: Used when ordinary bolts cannot meet the connection requirements, such as concrete roof trusses, roof beam suspensions, monorail beam suspensions, etc.
Overall, carbon steel coated black double headed bolts play an important role in the industrial field due to their structural stability, wide applicability, and ability to adapt to different connection requirements.
