Products Description
Hexagon Flange Nut
Hebei Sanwei Fasteners Co., Ltd.



The size and specification of flange nuts have a crucial impact on their application scope. The following are several key factors:
Application scenarios: Different application scenarios have different requirements for the size, material and performance of flange nuts. For instance, flange nuts of M5 and M6 specifications are typically used for connecting small components, while those of M12 and M20 specifications are suitable for connecting large pipelines and equipment.
Connection strength: The size of the flange nut directly affects its connection strength. Larger flange nuts can provide a greater contact area and higher load-bearing capacity, making them suitable for applications that bear heavy loads.
Material selection: The material of the flange nut also affects its application range. For instance, carbon steel flange nuts are suitable for general environments, while stainless steel flange nuts are appropriate for environments with higher requirements for corrosion resistance.

Product application

Mechanical manufacturing
Hexagonal flange nut are vital in heavy machinery such as excavators and mining equipment, where their anti-vibration flange design secures the frame and transmission components.
01

Automobile industry
In vehicles, they fasten chassis suspensions, engine blocks, and wheel hubs, with the flange preventing loosening from dynamic loads. Commercial trucks use them for frame-box connections, while their high load capacity suits axle fixing.
02

Construction field
In steel structures, they join beams and trusses, distributing pressure effectively for durability in vibrating environments like factory cranes.

Grade 4.8
Grade 4.8 is mostly made of low carbon steel, which is suitable for occasions with low strength requirements, such as ordinary furniture assembly, general mechanical connection.

Grade 8.8
Grade 8.8 multi-purpose medium carbon steel and after heat treatment and tempering, often used in automobile manufacturing

Grade 10.9
Grade 10.9 is often used for steel structure connection in bridge construction, which can withstand large loads; It is also more common in the connection of key parts of large machinery and equipment, such as mining machinery, port cranes, etc.,

Grade 12.9
Grade 12.9 is mainly used in the aerospace field, such as the connection of key components such as aircraft engines and landing gear, requiring bolts and nuts to have extremely high strength and reliability;
