The flange bolt is an integrated bolt composed of two parts: a hexagonal head and a flange plate (the gasket under the hexagon is fixed with the hexagon) and a screw (a cylinder with an external thread). It needs to be matched with a nut to fasten the parts connecting the two through holes.

Flange bolts: Flange bolts are an integrated bolt composed of two parts: a hexagonal head and a flange plate (the gasket under the hexagon is fixed with the hexagon) and a screw (a cylinder with an external thread). It needs to be matched with a nut to fasten the parts connecting the two through holes, so the bolted connection is a detachable connection.
classification：
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 plated with white, army green, color yellow, and corrosion-resistant dacromet.
3. Flange type: According to the different locations of the flange bolts, the size requirements of the discs are different. There are also flat-bottomed and toothed, and the toothed ones play a non-slip role.
4. According to the force method of the connection, there are ordinary and hinged holes.The flange bolts used for reaming holes should match the size of the holes and be used when subjected to transverse forces.
In addition, in order to meet the needs of locking after installation, there are holes in the rods, which can prevent the bolts from loosening when they are vibrated.
Some flange bolts have to be made in the parts of the light rod that are not threaded, which are called fine rod flange bolts.This kind of flange bolt is conducive to the connection of variable forces.Remarks: The national standard numbers commonly used in the market, GB5789 (big head) and GB16674 replace GB5787 (small head).
