 Hex Flange Bolt ,There are two kinds of hexagonal head, one is flat brain, the other is concave brain.

 surface color categories: according to different needs, the surface has white, military green, colored yellow, and never rusted Dacromet.

   flange category: according to the different locations of the flange bolts, the size requirements of the disc are different, and the flat bottom and the toothed points, with the anti-slip effect of the teeth.
                                      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 rods to be thin, called thin rod flange bolts. This kind of flange bolts are beneficial for the coupling of variable forces.

  There are special high-strength bolts on the steel structure. The head will be larger and the size will change.

The types of flanges one intends to bolt together do not necessarily require a special type of flange bolt, such as standard or metric. Instead, it is typically the physical size of a flange system, or the specific number of boltholes, that will indicate the required bolt size or grade one should use. The bolt grade indicates its strength, so the higher the grade a bolt has, the stronger it is. For example, high-pressure connections, such as in a steam line, may require grade eight bolts for the utmost reliability and safety.

A flange bolt is suitable with most any flange system. The sizes and grades, or strength ratings, can and will change depending on the application at hand. Sizes are available in standard or Society of Automotive Engineering (SAE) measurements, such as 1/4 inch and 1/2 inch, as well as metric measurements, such as 8mm and 10mm. Designed to hold connections tightly, without slippage or loosening, flange bolts are standard in most industrial applications where secure connections are crucial to production.
