DIN 934 is a standard published by the Deutsches Institut für Normung (DIN) that specifies the requirements for hexagon nuts. Hexagon nuts are a type of fastener commonly used to secure bolts, screws, and other threaded components.
The DIN 934 standard defines the dimensions and tolerances for hexagon nuts in both metric and inch sizes. The standard also covers the materials and heat treatment requirements for these nuts, as well as the testing methods used to evaluate their performance.
Overall, DIN 934 is an important standard for manufacturers and engineers who work with hexagon nuts. It helps ensure that these fasteners meet certain quality and performance standards, including strength, durability, and resistance to corrosion.
Uses of DIN 934
DIN Hexagon nuts that conform to the DIN 934 standard are commonly used in a variety of applications, including:
- Machinery assembly: Hexagon nuts are often used to secure bolts, screws, and other threaded components in machinery and equipment, where high strength and precision are required.
- Automotive applications: These nuts are used in automotive applications, such as engine assembly and suspension systems, due to their high strength and reliability.
- Construction and building: Hexagon nuts are used in the construction and building industries, such as in steel fabrication and structural engineering applications.
- Plumbing and piping: These nuts are used to connect pipes and fittings in plumbing and piping systems.
- Electrical and electronic applications: Hexagon nuts are also used in electrical and electronic applications, such as in the assembly of control panels and other equipment.
Overall, the DIN 934 standard ensures that hexagon nuts meet certain quality and performance standards, making them suitable for use in a wide range of industries and applications.
Materials for DIN 934
- Low carbon steel (ASTM A563 Grade A, C3, C4, D, DH)
- Medium carbon steel (ASTM A194 Grade 2H, 2HM, 7, 7M, 8, 8M)
- Alloy steel (ASTM A194 Grade 4, 4L, 9, 16, 16H, 16M, 29, 32)
- Stainless steel:
- Austenitic stainless steels (ASTM F594 Grade A, B, C, D, E, F)
- Martensitic stainless steels (ASTM A276 Grade 410, A479 Grade 410)
- Duplex stainless steels (ASTM A182 Grade F51, F53, F55)
- Non-ferrous metals:
- Brass (ASTM B16)
- Bronze (ASTM B98)
- Titanium alloys (ASTM F468 Grade 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12)
Note that these are just some examples of grades of materials that can be used to make DIN 934 hexagon nuts. The specific grade used for a particular nut may depend on the application requirements and the manufacturer's specifications. It's important to consult the manufacturer's documentation or markings on the nut to determine the specific grade used.
ISO 4032(DIN934) VS ISO 4033
- Thread pitch:
- ISO 4032 specifies the dimensions for hexagon nuts with metric coarse pitch threads.
- ISO 4033 specifies the dimensions for hexagon nuts with metric fine pitch threads.
- Nut thickness:
- Both standards specify that the thickness of the nut should be equal to the nominal diameter of the bolt it is used with.
- Material requirements:
- Both standards specify the material requirements for hexagon nuts, including the types of materials that can be used, as well as the chemical and mechanical properties required.
- Both standards specify the dimensions and tolerances for the various components of the hexagon nut, such as the width across flats, the thickness, and the thread length.
- ISO 4032 hexagon nuts are typically used in applications where a coarse pitch thread is required.
- ISO 4033 hexagon nuts are typically used in applications where a fine pitch thread is required.
Coarse pitch thread:
- ISO 4032 hexagon nuts are typically used in applications where a coarse pitch thread is required. Coarse pitch threads are used in applications where high strength and load-bearing capacity are required. Coarse pitch threads are also used in applications where fast installation is required, such as in construction, manufacturing, and assembly applications.
Fine pitch thread:
- ISO 4033 hexagon nuts are typically used in applications where a fine pitch thread is required. Fine pitch threads are used in applications where greater accuracy and finer adjustment are required, such as in machinery, equipment, and automotive applications. Fine pitch threads are also used in applications where vibration resistance and fastener locking features are required.
DIN 934 VS DIN 6915
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:
- 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.
- 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.
- 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.
- 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.
