DIN 558 specifies coarse-threaded hexagon head bolts, a common type of fastener used in various applications. These bolts feature a hexagonal head for easy tightening with wrenches and are known for their high strength and durability. The DIN standard defines the bolt's dimensions, including length, diameter, thread pitch, and material composition, ensuring compatibility and reliability across different manufacturers.

They are commonly used in industrial equipment, construction projects, and automotive systems. Choosing the right DIN 558 bolt is crucial for achieving a secure and reliable connection. Factors to consider include the required load capacity, environmental conditions, and material compatibility.

Hex Nut DIN 976 A

DIN 976 A outlines hexagon nuts with a fine thread pitch, designed for use in applications requiring precise threading. These nuts are manufactured to stringent tolerances and provide a robust connection. They are commonly used in automotive settings where high strength is essential. DIN 976 A nuts are available in a range of sizes and materials to suit diverse applications.

• Important attributes include:
• {A six-sided hexagon shape for easy handling with wrenches
• Fine thread pitch for precise adjustment and secure fastening
• Compliance with DIN 976 A standard ensuring quality and consistency

DIN 125 Hexagonal Washers

DIN 125 specifies DIN 931 the dimensions and tolerances for hexagonal washers. These elements are commonly used in applications where a large bearing surface is required, often with bolts or screws. The hexagon shape provides improved grip and prevents rotation, ensuring a secure attachment. The material ingredients can vary depending on the application, with common choices including steel, stainless steel, and brass.

• Manufactured from various materials like
• {Offering enhanced grip and stability|Providing improved grip and stability
• {Ideal for applications requiring a large bearing surface|Perfect for scenarios demanding a broad bearing surface

Bolts with Hexagon Head and Flange - DIN 975

DIN 975 defines a specific type of bolt known as a bolt with a hexagon head and flange. These fasteners are commonly utilized in industrial applications where a secure and robust connection is required. The hexagonal head provides a reliable grip for socket wrenches, while the flange ensures a stable platform. DIN 975 specifications outline various dimensions, including thread size and length, to accommodate diverse application needs. These fasteners are often manufactured from materials such as steel or stainless steel, chosen for their strength and durability.

• Uses of DIN 975 bolts encompass various industries, including automotive, construction, and machinery manufacturing.
• The flange design helps to distribute the load efficiently across a wider surface area, preventing stress concentration on a single point.
• Compliance with DIN 975 standards ensures consistent quality and performance of these screws.

German Standard

DIN 976 specifies the technical specifications for hexagon nuts. These nuts feature a hexagonal shape, which allows for easy tightening and loosening using a wrench. The standard outlines various measurements, compositions and specifications. DIN 976 hexagon nuts are widely used in a wide scope of industries, such as automotive, construction, and machinery.

• Often {used materials for DIN 976 nuts include steel, stainless steel, and brass.
• The standard also deals with the surface treatment of hexagon nuts to enhance durability to environmental factors.
• Compliance with DIN 976 ensures consistency of hexagon nuts within manufacturing processes

Comparing DIN 975 & DIN 976

When picking bolts and nuts for industrial applications, it's essential to understand the differences between various standards. Two common specifications in the European market are DIN 975 and DIN 976. While both offer hexagonal head screws with corresponding nuts, they vary in crucial aspects. DIN 975 bolts are typically applied for applications requiring a more robust connection, while DIN 976 bolts are often selected for less demanding uses.

A key distinction lies in the thread form. DIN 975 bolts utilize a coarse thread pitch, guaranteeing higher tensile strength. On the other hand, DIN 976 bolts feature a less coarse thread pitch, which facilitates smoother installation and lowers torque requirements.

• Furthermore, the material composition can also differ between the two standards. DIN 975 bolts are commonly made of alloy steel, while DIN 976 bolts may be manufactured from various materials, including zinc-plated carbon steel.
• Understanding these distinctions is crucial for selecting the appropriate bolt and nut combination for a specific application.
