Do you know DIN6921 Hex Flange Bolts?

DIN6921 Hex Flange Bolts, or DIN6921 hexagonal flange bolts, are a widely used fastener, and their design and manufacturing follow the DIN6921 standard.

1. Main features

Hexagonal flange design: The bolt head adopts a hexagonal flange shape, which increases the contact area with the connecting piece and improves the stability and load-bearing capacity of the connection.

High strength: According to different materials and strength grades, DIN6921 hexagonal flange bolts can withstand large tensile and shear forces and are suitable for various heavy loads and vibration environments.

Corrosion resistance: Made of high-quality materials such as stainless steel, it has good corrosion resistance and is suitable for humid and corrosive environments.

2. Material and strength grade

Material: Mainly includes carbon steel, stainless steel, alloy steel, etc. The specific choice depends on the use environment and requirements.

Strength grade: Common strength grades are 8.8, 10.9, 12.9, etc. The larger the number, the higher the tensile strength and yield strength of the bolt.

3. Application fields

DIN6921 hexagon flange bolts are widely used in mechanical equipment, bridge construction, automobile manufacturing, aerospace and other fields, providing reliable fastening solutions for various connections.

4. Precautions

Correct selection: When selecting DIN6921 hexagon flange bolts, it is necessary to comprehensively consider factors such as the material, thickness, and working environment of the connecting parts to ensure the correct selection.

Standard installation: During installation, relevant standards and specifications must be followed to ensure that the bolt tightening torque is appropriate to avoid over-tightening or over-loosening that may cause connection failure.
