A hex flange bolt is a type of bolt that features a hexagonal head and a flange. The hexagonal head allows for easy tightening and loosening using a wrench or other suitable tools. The flange, which is a circular or annular projection at the base of the head, provides several advantages.
The hex part of the bolt, with its six - sided shape, offers a reliable and firm grip when being turned. This design enables precise torque application, ensuring that the bolt is tightened to the appropriate level.
The flange serves multiple purposes. It increases the bearing surface area, which helps to distribute the load more evenly when the bolt is tightened. This reduces the risk of damage to the material being fastened and provides better resistance against loosening due to vibrations.
Hex flange bolts are widely used in various industries and applications. In the automotive industry, they are commonly employed to secure engine components, chassis parts, and body panels. Their ability to withstand high - stress conditions and vibrations makes them ideal for these applications.
In construction, they are used to connect structural members, such as in the assembly of steel frames, where the even load distribution provided by the flange is crucial for the integrity of the structure.
They are also found in machinery and equipment manufacturing, being used to fasten different parts together, ensuring the stability and reliability of the machinery during operation.
Hex flange bolts are typically made from high - strength steel to provide the necessary tensile strength and durability. Stainless steel is often used in applications where corrosion resistance is required, such as in outdoor or marine environments.
To further enhance their performance and protect against corrosion, they may be subjected to various surface finishes. Common finishes include zinc plating, which provides a sacrificial layer to prevent rust, and black oxide coating, which not only offers some corrosion protection but also gives a more aesthetically pleasing appearance.
In summary, the hex flange bolt is a versatile and essential fastening component, valued for its combination of a hexagonal head for easy handling and a flange for improved load - distribution and anti - vibration properties, making it suitable for a wide range of applications in different industries.

Hex flange bolts, also known as hex flange machine screws, incorporate a bearing face, or flange, that extends beyond the diameter of the head. This flange distributes the clamp load over a larger area. Some flange machine bolts feature locking serrations on the face of the flange that are designed to “lock,” or bite, into the material being fastened to provide resistance to loosening. HAIYAN offers a wide selection of metric and standard flange machine bolt sizes with lengths ranging from 1/4” up to 4”. HAIYAN is a distributor of hex flange machine screws and offers both convenient small package sizes as well as large bulk packaging. Many of our flange machine bolts require a quote, which allows us to offer the best prices. Please contact us today – our experienced sales team is ready to help!
