A flange bolt is a fastener characterized by a skirt that extends outward from the head at a 360-degree angle. Flange bolts are named for the round flange underneath the head. Hexagonal flange bolts can be categorized into different types based on different classifications.

• Hexagonal head type: one is flat-brained and the other is concave-brained.
• Surface color category: according to different needs, the surface is plated with white, military green, color yellow, corrosion-resistant Dacromet.
• Flange category: according to the use of flange bolts in different locations, the size of the disk requirements are different, and there are flat bottom and with the teeth of the points, with the teeth of the role of anti-slip.
• According to the connection of the force mode, there are ordinary and reamed holes with. The flange bolts for reamed holes should be matched with the size of the holes and used when subjected to transverse force.
