The button head flanged bolt is designed with a button head, a flange, and a threaded shaft. The button head makes the installation and removal easier. The flange increases the surface area of contact between the bolt and the connected parts, which helps to reduce the risk of damage to the surface.
The underside of the flange often features grooves or serrations to increase friction, preventing the bolt from loosening. One of the key advantages is that it eliminates the need for additional washers, which saves more time and improves efficiency during installation.
The button head flanged bolts are normally made of steel and stainless steel, they can be made of different surface finishes such as zinc plating, military green, yellow, or corrosion-resistant Dacromet coatings, which makes them suitable for various environments.
They are commonly used in automotive, industrial, and construction applications, button head flanged bolts are ideal for securing components in vibrating or high-stress settings. Their design ensures a stable, long-lasting connection that can withstand harsh conditions.
