1. Hexagonal head type: one is flat-brained, and the other is concave-brained. 2. Surface color category: According to different needs, the surface is coated with white, army green, color yellow, and corrosion-resistant dacromet. 3. Flange plate category: according to the different use positions of flange bolts, the size of the plate is different. There are also flat-bottomed and toothed ones. The toothed ones play an anti-slip effect. 4. According to the force mode of the connection, there are ordinary and reamed holes. The flange bolts used for reaming holes should be matched with the size of the hole and used when subjected to lateral force.
