the
Heavy Duty Bolt
The HD, or Heavy Duty Bolt was developed to address the need for a shorter blind fixing with improved performance where a shear plane would fall across the legs of a Blind Bolt.
With its expanding base and unique pin locking mechanism the HD bolt is the idea fixing solution between heavy weight steel sections. The HD bolt employs a simple activation method designed to reduce installation time and expense. A hammer and a spanner are all thats required to activate the Heavy Duty Bolt removing the need for costly specialist equipment required with similar products.
- Quick and easy to install Hd2.
- No oversized hole required.
- Finished with Geomet 500B coating giving 1000 hours salt spray protection.
- Increased assembly efficiency.
- Unique pin locking design.

Testing Data Explained
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.
Due to the unique properties of the HD Bolt there are certain operation criteria that must be met to ensure its successful application.
Use the menu to see an explanation of the testing criteria found on our technical data sheets. However, if there is anything that you are unsure about please feel free to contact us on the number below or click here to send us an e-mail.
This is the minimum distance that the bolt is able to clamp.
This is calculated from the overall thickness of all materials being clamped.
This is the maximum distance that the bolt is able to clamp.
This is calculated from the overall thickness of all materials being clamped.
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.
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.
This is the ultimate pullout force required for the bolt to fail when under a tensile load.
