The Original Expansion Bolt for Structural Applications

Making connections between materials such as hollow section can be tricky, especially when there is only access on one side. Welding is often the only option. But thanks to Lindapter, Hsfastener is pleased to bring you the smart alternative for fastening structural hollow section (SHS/HSS): Hollo-Bolt. Not just any blind bolt, this product provides features never before seen on inferior competitive options. The Hollo-Bolt saves time on installation, lowers labour costs, is easy to install from one side, is perfect for SHS, requires no welding, has a higher resistance to shear and tension, has an immense clamping force, comes in different corrosion resistant options, makes aesthetically-pleasing connections and is independently approved for performance. For use in structural frames, glazing and roofs, staircases and handrails, balconies and canopies, facades, cladding, towers and masts, get in touch with Allfasteners now, For All Things Fixings…and the perfect blind bolt.

Easy to Install

Simply insert the fastener into a pre-drilled hole in the hollow section and tighten it with a torque wrench. No welding is required, thanks to the Hollo-Bolt’s patented HCF mechanism: upon torqueing, the threaded component—inserted into the bolt’s hollow core—retrieves the nut back into the expanding sleeve section, creating a grip that is highly-resistant to shear and tension forces.

Hollo-Bolts Applications

Without no need to cut access holes or for brackets or strapping, installation is fast and secure. There are also options for different head types and finishes, depending on environmental factors or tool access.

Head types:

Hexagonal – preferred for most SHS connections, or where architectural ‘industrial look’ is required.
Countersunk (head) – with a special collar designed to accommodate the entire bolt head.
Flush fit – to be entirely concealed into a countersunk hole.

Finishes:

Bright zinc-plated & JS500
Hot dip galvanised
Sheraplex*
316 stainless steel

Sizes:

M8, M10, M12, M16 and M20
These common diameters are available in 3 lengths allowing for incremental thickness of material to be joined.

*A two-stage treatment process that first involves Sheradising (zinc coating), then an organic barrier layer. The resulting surface has a smooth matt grey finish that provides high corrosion resistance.
