JIS B1189 is the Japanese Industrial Standard (JIS) for hexagonal flange bolts. This type of bolt has a hexagonal head and a flange surface, which is usually used to increase the contact area with the connecting parts, thereby improving the stability and reliability of the connection. These bolts are usually made of metal materials such as steel and have high strength and durability. The surface of the bolt may be treated with blue and white zinc plating to improve its corrosion resistance and aesthetics.
