DIN 6915

DIN 6915 is a German Industrial Standard that specifies the requirements for high-strength structural nuts with large width across flats and metric coarse and fine pitch thread made of steel. These nuts are designed for use in high-strength structural applications, where they can withstand high loads and provide reliable joint connections. By adhering to DIN 6915, manufacturers can ensure that their high-strength structural nuts are manufactured to the necessary quality and safety standards. DIN 6915 nuts have a thicker height and larger width across flats compared to standard hexagon nuts, providing increased surface area for greater clamping force.

Uses of DIN 6915

High-strength structural nuts with large width across flats and metric coarse and fine pitch thread made of steel, as specified by DIN 6915, are commonly used in various applications, including:

1. Structural steel construction: They are used in the construction of buildings, bridges, and other large structures, where they serve as fasteners for high-strength bolts and other components.
2. Industrial machinery: They are used in the manufacturing of heavy-duty machinery and equipment, where they serve as fasteners for bolts and other components.
3. Automotive industry: They are used in the automotive industry as well, specifically for applications where high-strength fasteners are required.
4. Power generation: They are used in the power generation industry, specifically for applications involving the construction and maintenance of large turbines, generators, and other equipment.

In summary, high-strength structural nuts with large width across flats and metric coarse and fine pitch thread made of steel, as specified by DIN 6915, are used in various industries and applications, including structural steel construction, industrial machinery, automotive, and power generation. These nuts provide reliable joint connections and are able to withstand high loads, making them ideal for use in high-strength applications.

Materials for DIN 6915

DIN 6915 specifies the requirements for high-strength structural nuts with large width across flats and metric coarse and fine pitch thread made of steel. The following are the ANSI, ASME, ASTM, and DIN standard materials that can be used to make these nuts:

1. Steel: The most common material used to make DIN 6915 nuts is steel. The specific grades of steel that can be used include:

• ANSI/ASME B18.2.2: Grades 2, 5, and 8
• ASTM A563: Grades A, C, DH, and DH3
• DIN EN ISO 898-2: Property class 10, 10.9, 12, 12.9

2. Stainless Steel: Stainless steel can also be used to make DIN 6915 nuts. The specific grades of stainless steel that can be used include:

• ANSI/ASME B18.2.2: Grades 304 and 316
• ASTM F594: Grades A, B, and C
• DIN EN ISO 3506-2: A2-70 and A4-70

ISO 4032(DIN934) VS ISO 6915

It is important to select the appropriate material and grade based on the specific application requirements. By adhering to the necessary standards and specifications, manufacturers can ensure that their high-strength structural nuts are manufactured to the necessary quality and safety standards.

DIN 934 and DIN 6915 are two different German Industrial Standards that specify the requirements for hexagon nuts with metric coarse and fine pitch thread. Here are the main differences between the two standards:

1. Material: DIN 934 covers hexagon nuts with metric coarse and fine pitch thread made of steel, while DIN 6915 covers high-strength structural nuts made of steel.
2. Strength: DIN 934 nuts have a lower strength class than DIN 6915 nuts. DIN 934 nuts are typically used in applications with moderate loads, while DIN 6915 nuts are designed to withstand higher loads and are used in structural applications.
3. Size: DIN 934 covers a wider range of sizes than DIN 6915. DIN 934 covers nuts with a diameter range of M1.6 to M64, while DIN 6915 covers nuts with a diameter range of M12 to M36.
4. Dimensions: DIN 6915 nuts have a thicker height and larger width across flats compared to DIN 934 nuts. The thickness of the nut in DIN 6915 is equal to the nominal diameter of the bolt, while the width across flats is typically larger than that of DIN 934 nuts.

Overall, DIN 6915 nuts are designed for use in high-strength structural applications, while DIN 934 nuts are suitable for moderate-load applications. DIN 6915 nuts have a thicker height and larger width across flats compared to DIN 934 nuts. It is important to select the appropriate standard and nut type based on the specific application requirements.
