DIN931-1 ISO4014 Hexagon Head Bolts Partially Threaded Galvanize Carbon Steel 35K/Alloy Steel 40Cr Class 8.8 10.9

DIN931 Hexagonal Head Bolts with Partial Thread are bolts that adhere to the technical specifications set by the Deutsches Institut für Normung (DIN), the German Institute for Standardization. These bolts exhibit several key features and benefits, making them suitable for various engineering applications.

Structural Characteristics:

  • Head Design: The bolts feature a hexagonal head, which allows for easy installation and removal using tools such as wrenches or socket wrenches.
  • Thread Section: The bolts have a partial thread, meaning that only a portion of the shank is threaded. This design is suitable for applications where the bolt needs to pass through a component and be tightened with a nut on the other side.

Standardization and Specifications:

  • DIN931 Standard: The bolts comply with the DIN931 standard, ensuring consistency and reliability in terms of dimensions, materials, and performance.
  • Range of Sizes: They are available in a wide range of thread sizes from M1.6mm to M64mm and shank lengths from L12mm to L500mm, catering to diverse engineering needs.

Materials and Performance:

  • Material Requirements: DIN931 hexagonal head bolts are typically made from high-strength materials such as carbon steel, alloy steel, or stainless steel. These materials offer excellent mechanical properties, corrosion resistance, and durability.
  • Performance Grades: Depending on the material and size, the bolts have various performance grades, such as 8.8 and 10.9 for steel bolts and A2-70 and A4-70 for stainless steel bolts.

Application Areas:

  • DIN931 hexagonal head bolts with partial thread find applications in various industries, including machinery, automotive, shipbuilding, and construction. They are used for fastening structural components, connecting pipes, installing equipment, and other purposes, ensuring secure and reliable connections.

Advantages:

  • Easy Installation and Removal: The hexagonal head design facilitates efficient rotation using tools, improving work efficiency.
  • Flexibility: The partial thread design allows for flexibility in different connection scenarios.
  • Reliability and Durability: The use of high-strength materials and adherence to DIN931 standards ensures the bolts' reliability and durability, meeting the demands of various engineering applications.
