Product Description

Product Overview:

Double arming bolts are specialized fasteners typically made from galvanized steel, designed to bridge and secure two separate clamp connections. The term ‘double’ refers to their ability to connect and stabilize two points simultaneously. These bolts feature equal thread lengths at both ends with a raised, unthreaded center section where equipment can hang. They are essential in ensuring the structural integrity and stability of utility poles and other structural applications.

Structural Features:

  1. Fully Threaded Design:
    • The bolts are fully threaded at both ends, providing strong and secure connections.
  2. Square Nuts Included:
    • Each bolt comes assembled with 4 square nuts, ensuring secure and stable fastening.
  3. Compatibility with Eye Nuts:
    • The ends of the bolts can accept eye nuts, making them suitable for dead-end applications.
  4. Raised Center Section:
    • Features a raised, unthreaded center section where equipment can be securely hung, ensuring proper alignment and stability.

Material:

  • Made from steel, hot-dip galvanized to provide excellent durability and resistance to corrosion, ensuring long-term performance even in harsh environmental conditions.

Installation Method:

  1. Preparation:
    • Ensure all necessary tools and materials are available before starting the installation process. Verify the specifications of the double arming bolts to ensure compatibility with the application.
  2. Positioning:
    • Align the bolt with the pre-drilled holes in the two structures or components to be connected.
  3. Inserting Bolts:
    • Insert the bolt through the aligned holes, ensuring the raised center section is properly positioned.
  4. Securing Nuts:
    • Attach the square nuts to both threaded ends of the bolt and tighten them securely using appropriate tools.
  5. Inspection:
    • Inspect the installation to ensure the bolts are securely fastened and the connection between the two components is stable and aligned.

Applicable Environmental Conditions:

  1. Temperature Range:
    • Suitable for operation in temperatures ranging from -40°C to +85°C, ensuring performance in extreme weather conditions.
  2. Humidity:
    • Can operate effectively in environments with high humidity, providing reliability in moist conditions.
  3. Weather Resistance:
    • Designed to withstand harsh weather conditions, including high winds, heavy rain, and UV exposure.

Product Advantages

  • 1. Good reliability: When the stud is connected, there is no need to add accessories such as matching pins, which can greatly improve the reliability of the connection.
  • 2. Strong rigidity: When the stud is connected, the components are tight and can provide a good fixing effect.
  • 3. Easy installation: the double bolt is more convenient than the traditional single bolt due to the increase in the number of thread heads.
  • 4. Anti-loosening effect: When the two thread heads of the stud are connected, the docking parts can be more stable, so as to avoid loosening.
