Hex flange bolt DIN6921
The hex flange bolt is a fastener with a hexagonal head and an integral flange at the base of the head. The flange provides a wider bearing surface under the head, which distributes the load and helps to eliminate the need for a separate washer. This design is intended to provide a more secure and stable fastening in applications where vibration or movement may be a concern.
In terms of structure, the hex flange bolt typically consists of a threaded shank, a hexagonal head, and an integrated flange. The shank is designed to be inserted into a pre-tapped hole or through a clearance hole and then secured with a nut on the opposite side. The hexagonal head allows for easy tightening and loosening with a wrench or socket, while the flange provides the additional benefits mentioned earlier.
Classification of hex flange bolts can be based on factors such as material, thread type, and size. They are available in various materials including steel, stainless steel, and other alloys, and can be classified based on thread type such as coarse thread or fine thread. Additionally, they come in different sizes and lengths to accommodate a wide range of applications.
