This product consists of a steel hexagon head fine pitch long shank power bolt, a corresponding hex nut, and a flat washer. This assembly is designed for applications requiring high clamping force, precise adjustments due to the fine pitch thread, and the ability to bridge larger distances or pass through thick materials with its long shank. The flat washer helps distribute the load and protect the mating surface.

Key Components:

• Steel Hexagon Head Fine Pitch Long Shank Power Bolt:
  • Material: Made from high-strength steel (specific grade may vary based on application, e.g., Grade 8.8, 10.9, 12.9) for durability and load-bearing capabilities.
  • Head Type: Hexagon head, designed for easy tightening with spanners or sockets, providing good grip and torque transmission.
  • Thread Type: Fine pitch thread, offering several advantages:
    • Increases resistance to loosening under vibration.
    • Allows for finer adjustments and more precise clamping.
    • Provides higher strength due to a larger minor diameter and greater stress area compared to coarse threads of the same nominal size.
  • Shank: Long shank, indicating a significant unthreaded portion between the head and the threaded section. This is useful for:
    • Spanning larger gaps or passing through thick components without the threads bearing unnecessary stress.
    • Reducing the stress concentration in the threaded area, potentially improving fatigue life in some applications.
  • “Power Bolt” Designation: Implies the bolt is designed for high-strength, heavy-duty applications where significant power or load transfer is required. This often correlates with higher tensile strength and robust construction.
• Hex Nut:
  • Material: Typically made from steel, compatible with the bolt’s material and strength grade to ensure a secure and durable connection.
  • Design: Hexagonal shape for easy engagement with wrenches, designed to match the bolt’s fine pitch thread.
• Flat Washer:
  • Material: Usually steel, chosen to be compatible with the bolt and nut.
  • Function:
    • Distributes the clamping load over a wider area, reducing the pressure on the mating surface.
    • Prevents damage to the surface under the nut or bolt head during tightening.
    • Can help prevent loosening by providing a uniform bearing surface.

Typical Applications:

This bolt assembly is ideal for demanding applications where precision, high strength, and a long reach are critical:

• Heavy machinery and equipment assembly (e.g., presses, industrial robots)
• Structural steel connections where precise alignment and robust fastening are needed.
• Automotive and aerospace applications, particularly in engine components or critical airframe structures.
• Bridge construction and infrastructure projects, especially in areas subjected to vibration and high loads.
• Any application requiring a strong, rigid connection over a considerable thickness of material, with the added benefit of fine adjustment.

Advantages:

• High clamping force and superior resistance to loosening due to fine pitch threads.
• Accommodates thick materials or wider gaps with its long shank.
• Enhanced load distribution and surface protection provided by the flat washer.
• Suitable for high-stress and critical fastening applications.
