    Testing & Fixing Terms - Use the slider to browse through the different fixing and testing terms for the HD Bolt

  • background

    Minimum Fixing Thickness

    This is the minimum distance that the bolt is able to clamp.
    This is calculated from the overall thickness of all materials being clamped.

  • background

    Maximum Fixing Thickness

    This is the maximum distance that the bolt is able to clamp.
    This is calculated from the overall thickness of all materials being clamped.

  • background

    Tensile Strength

    This is the ultimate pullout force required for the bolt to fail when under a tensile load.

    Depth Clearance

    Depth Clearance is the minimum distance required within a cavity to allow the Heavy Duty Bolt's legs to deploy.
    Careful attention must be payed to this criteria when fixing into Steel Hollow Sections to prevent the bolt reaching the opposite section wall before the bolt has been installed correctly.

    Shear Strength Over Thread

    This is the ultimate force required for the bolt to fail when the shear plane, produced by the two materials being clamped, falls over the threaded portion of the bolt.

HD Bolt Fixing and Testing Terms Explained
