The flange bolt consists of a hexagonal head and a flange (the gasket under the hexagon and the hexagon is fixed) and the screw (the cylinder with the external thread). The integral bolt needs to be matched with the nut for fastening. A part that connects two through holes.
Flange bolts: This type of connection is called a bolt connection.
If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
1, hex head type: one is flat brain, the other is concave brain.
2, surface color categories: according to different needs, the surface has white, military green, colored yellow, corrosion-resistant Dacromet.
3. Flange category: According to the different positions of the flange bolts, the size requirements of the discs are different, and the flat bottom and the teeth are divided, and the teeth have the anti-slip effect.
4. According to the way of connection, there are common and reamed holes. The flange bolts used for the reaming holes should match the size of the holes and be used when subjected to lateral forces.
In addition, in order to meet the needs of locking after installation, there are holes in the rods, which can make the bolts not loose when they are vibrated.
Some flange bolts have no threaded polished rod parts, called thin rod flange bolts. This kind of flange bolts are beneficial to the coupling of variable forces.
