Flange bolts are threaded fasteners with a built-in wide flat flange (round or hexagonal edge) under the head, which can disperse pressure, prevent component damage, and improve stability. They are driven by tools and used in pipes, machinery, and automobile fields. They are mostly made of steel or stainless steel.
Flange bolts, also known as flange connection bolts, are important fasteners, consisting of bolts, nuts and flanges. They can achieve reliable mechanical connections and are used in many fields such as pipelines and pressure vessels. According to the material, it is divided into two categories: carbon steel and stainless steel. The former has good strength and corrosion resistance and is used in general engineering; the latter has excellent corrosion resistance and high temperature resistance and is suitable for high corrosion and other occasions. In use, it is used to ensure stable operation in the connection of pipelines, pressure vessels, and chemical equipment, to ensure hull sealing and structural strength in shipbuilding, and in the aerospace field to connect aircraft and rocket components.
