It is usually high-strength steel with six flanges and a central threaded hole. DIN EN ISO 21670 Welded Hexagon Flange Nut The primary function of the DIN EN ISO 21670 Welded Hexagon Flange Nut is to connect threaded rods or bolts with other components and play a role in fixing and fastening.

Definition and Classification of Automotive Welded Hex-Flanged Nuts

DIN977 Welded Hexagon Flange Nut is a special kind of nut, suitable for use in conjunction with the welding process, usually made of a weldable material, relatively thick, and ideal for the high-temperature welding process. DIN977 welded hexagon flanged flange nuts play an important role in many industrial and consumer products such as automobiles, machinery, electronic equipment, instruments, etc. They have internal threads and are used in conjunction with screws to transmit motion or power. When installing them, it is often necessary to ensure that the welding position is correct and that the quality of the welding process is maintained to provide a robust and reliable connection. In addition, the application of DIN977 welded hexagon flange nuts also involves aerospace parts, ship parts, steel structure buildings, and other fields.

An Automotive welded hex flange nut is a connecting element that welds the nut to the automobile body, which usually consists of two parts: the nut and the welded substrate. According to specific application scenarios and shapes, automotive welded nuts can be categorized into various types: large nuts, shaped nuts, round welded nuts, square welded nuts, hexagonal welded nuts, and welded hexagonal flange nuts.

Advantages of automotive welded hexagon flange nuts

The following aspects mainly reflect the structural features of the JIS B 1200 Welded Hex Flange Flange Nut. First, its six flanges provide greater tightening force, enabling it to withstand greater loads. Secondly, the central threaded hole of the Welded Hexagon Flange Nut is processed with high precision to accurately match the threaded rod or bolt to ensure its fastening effect. In addition, welded hexagon flange nuts have good corrosion and abrasion resistance and can be used long in harsh environments.

The manufacturing process of JIS B 1200 welded hexagon flange nuts generally includes the following steps. First, suitable steel is selected, cut, and shaped according to the design requirements. Then, the threaded holes are machined into the nut body by cold heading or hot forging processes. Next, the nut body and hexagonal flange are positioned and aligned, then firmly connected by welding. Finally, surface treatment, such as galvanizing or heat treatment, is performed to improve the corrosion and wear resistance of the welded hex flange nut.

Compared with the traditional methods of machining and threaded connection, automotive welded nuts have the following advantages:

1. High strength: DIN977 welded hexagon flange nuts do not require threaded connection and can be welded directly, so the weld joints are more robust and can withstand greater loads and impacts.

2. Wear resistance: DIN977 welded hexagonal flange nuts are made of high-strength alloy material with solid wear and corrosion resistance and can extend the service life.

3. Safe and reliable: DIN977 welded hexagonal flange nut welding parts are uniform, robust, and not easy to cause loosening or falling off, thus enhancing the stability and safety of the automobile structure.

In summary, the automotive DIN977 welded hexagon flange nut is an essential connecting element with fixed, safe, reliable, and other advantages. It can be widely used in automotive manufacturing and maintenance and is vital in improving the stability and durability of the automobile structure.

DIN 977 Welded hexagon flange nuts for automotive applications

ISO 21670 welded hexagon flange nuts have various mechanical and structural engineering applications. They can connect components such as steel structures, mechanical equipment, bridges, pipelines, etc. Welded hexagon flange nuts play a vital role in engineering because of their fastening solid force, stability and reliability, and ability to withstand large loads.

Welded automotive nuts have a wide range of applications in the design and manufacture of automotive structures and are mainly used in the following areas:

1. Automotive body welding: automotive ISO 21670 welded hexagonal flange nut can be welded together with the nut and the automotive body to enhance the body stiffness and durability to prevent safety hazards caused by body deformation.

2. Automobile parts connection: ISO 21670 welded hexagonal flange nuts can connect automobile parts, such as doors, windows, and other car parts, to be fixed and reliable and avoid loosening or falling off.

3. Automotive electrical equipment welding: Automotive ISO 21670 welded hexagonal flange nuts are widely used to install and fix automotive electrical equipment, such as batteries and engine control modules.

DIN977 Automotive Welding Hexagon Flanged Nuts Correct Installation Methods

1. First of all, choose the proper nut. Select the appropriate nut According to the weldment or connector's specifications. Avoid using too large or too small ISO 21670 welded hexagon flange nuts.

2. Check whether the ISO 21670 welded hexagon flange nuts are complete and free of apparent damage, deformation, or other defects.

3. Insert the weldment or connector into the hole of the DIN 977 welded hexagon flange nut and manually rotate the nut to reach the tightness. Be careful not to rotate it violently with tools. Otherwise, it will cause damage.

4. When tightening the nut, keep the plane of the ISO 21670 welded hexagonal flange nut parallel to the weldment or connector. This can make the force distribution of the weldment or connector evener and reduce the force area.

5. Finally, use a wrench to loosen the nut by turning it counterclockwise, and then check whether the ISO 21670 Welding Hexagon Flange Nut has been fixed.

How do we check the installation of DIN977 automotive welded hexagon flange nuts?

Weld these nuts to flat, uneven, uncoated steel surfaces for a solid permanent hold. A collar pilot assists alignment and prevents welding spatter from getting into threads.

All nuts meet ASME B1.1 and comply with specifications for dimensional standards.

1. Sensitivity check: Use a rotating wheel to drive a copper plate and connect the nut between the wheel and the copper plate. Then, rotate the wheel by a certain angle and observe whether the copper plate is rotating. If it is, it means that the nut is not fixed.

2. Axial force check: Use a manometer to fix the nut on the weldment or connection and apply a specific axial force to observe whether the nut is loose.

Installation of ISO 21670 Welded Hexagon Flanged Flange Nuts Precautions

1. When installing DIN 977 automotive welded hexagon flange nuts, pay attention to the nut's installation direction and choose the correct direction according to its characteristics.

2. Use professional tools for fastening; do not use violence.

3. After installation, be sure to check the installation of the nut to ensure the safety and reliability of the weldment or connection.

In short, the DIN 977 automotive welding hexagon flange nut installation direction should pay special attention to the correct nut installation, which can improve the service life of the weldment or connection and protect production safety!

The ISO 21670 welded hexagon flange nut is a standard fastener with fastening solid force, structural stability, good corrosion resistance, etc., and has been widely used in mechanical and structural engineering.
