Hexagon flange bolt is a special structure bolt. It has an additional flange under the head of the ordinary hexagonal bolt. The presence of the flange increases the contact area between the bolt and the connection surface, which can effectively disperse the pressure. This structure can also reduce the pressure on the surface of the connected parts, thus enhancing the stability of the connection and preventing the parts from being damaged due to excessive localized pressure.

 

Hexagonal flange bolts are available in a wide variety of materials, including carbon steel, stainless steel, etc., and suitable bolts can be selected according to different usage environments and strength requirements.

 

In terms of size specifications, they include a variety of standard models such as metric and imperial to meet the assembly requirements of various types of machinery, construction, automotive and other industries. This kind of bolts is suitable for the occasions that need high connection reliability and have requirements for pressure distribution, such as the assembly of automobile engines, pipeline connections and the fixing of some large mechanical equipment. Both to ensure the fastening effect, but also to a certain extent to make up for the ordinary hexagonal bolts in some cases of shortcomings.
