TW Bolt Testing Terms Explained

TW Bolt Testing Terms Explained

Due to the unique properties of the TW Bolt there are certain operation criteria that must be met to ensure its successful application. These dimensions are outlined below, please use the menu above the picture to isolate each dimension and testing term to view a brief description.

However, if there is anything that you are unsure about please feel free to contact us on the number at the top of your screen or send us an e-mail.

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.

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.

The dimensions given are those of the standard bolt, however, the maximum fixing thickness can be greatly extended using a kit of extension sleeves.

Please contact us for more specific information

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 Thin Wall 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.
