A type of fastener known as a "hex flange bolt" is distinguished by its hexagonal head and integrated flange underneath it. Standard wrenches or sockets can be used to easily install and remove the hexagonal head, and the flange's greater bearing surface uniformly distributes the load and helps to keep the material being secured from loosening or being damaged. When a safe, vibration-resistant connection is needed, these bolts are frequently utilised in construction, equipment, and automotive applications. A separate washer component is not necessary because the flange can also function as a washer.
