Strutbolt Expansion Anchor
Approved expansion anchor for seamless hollow sections
Allows joints to be made in hollow sections when it is not possible to access the inside of the base material, replacing traditional fastening methods such as through-bolting or welded joints.
ETA Approved for structural applications.
Why choose STRUTBOLT?
Structural joints without welding
Allows metal-to-metal fastenings without welding, reducing construction time and labour costs.
Installation without rear access
Allows fastening when it is not possible to access the inside of the profile.
Outer sleeve with hexagonal head
The hexagonal head of the outer sleeve allows the anchor to be tightened from different angles, facilitating assembly.
Clean and safe installation
Simple installation that eliminates the combustion risks associated with welding work.
Homologated anchor
It has ETA approval, confirming the performance of the anchor in structural applications for high loads.
Expansion anchor designed for hollow profiles
In metal structures with hollow profiles, the rear side of the base material is not always accessible. In these cases, STRUTBOLT allows structural fastenings to be made without resorting to welding.
- Fastening of metal profiles to metal structures.
- Metal-metal structural joint.
- Joining of steel structural elements and other non-structural elements.
- Fixings in hollow profiles or blind materials without access to the inside.
- Applications subject to high loads.
- Can be used in rectangular, square and circular profiles with restricted access to the outer face.
Installation process
The installation of the STRUTBOLT is clean, simple and intuitive.
FAQS
What is an expansion anchor for hollow sections?
An expansion anchor for hollow sections is a fastening system designed to create connections in structural sections where access is only available from the outside.
Upon installation, the anchor expands within the section, creating a secure fastening without the need to access the interior of the structural element. STRUTBOLT is designed for this type of application in metal sections.
What advantages does an expansion anchor for hollow sections offer over a welded joint?
An expansion anchor for hollow sections such as STRUTBOLT allows metal-to-metal structural joints to be made without the need for welding, reducing installation times, minimising risks associated with hot work and simplifying on-site work.
What is the difference between an expansion anchor for hollow sections such as STRUTBOLT and a through-bolt?
A through-bolt requires access to both sides of the section to fit the nut. In contrast, an anchor for hollow sections such as STRUTBOLT is installed from a single side and expands inside the section, allowing the fastening to be carried out without subsequent access.
Can STRUTBOLT be used in concrete?
No. STRUTBOLT is an interference-fit expansion anchor designed specifically for use in hollow steel sections or structural sections where access is only available from one side of the base material.
