Concrete Wall Expansion Hook Anchor
Products Description

The concrete wall expansion hook anchor is a type of mechanical expansion fastener; its core feature is the use of the expansion force generated during installation to create a tight bond between the anchor assembly and the base material.
The product primarily consists of the following components:
Threaded anchor body
Expansion sleeve
Conical expansion mechanism
Hook-end structure
Surface protective coating
During installation, tightening or hammering causes the expansion component to expand outward, creating a mechanical interlock with the concrete hole wall and thereby providing stable load-bearing capacity.
Key product advantages include:
Reliable fixation and high tensile strength
Simple installation and high construction efficiency
Suitability for various wall structures
Long-term stability
Ability to meet the requirements of diverse engineering environments
Details and Quality Assurance
Thread Details
The thread surface is smooth and free of burrs or malformed threads, ensuring seamless engagement. The thread roots feature a radiused profile to minimize the stress concentration factor.
Radiused Hook Section
The Hook Sleeve Anchor opening is chamfered to prevent abrasion on wire ropes or chains during suspension, thereby protecting the suspended components.
Expansion Sleeve Slits
The slits in the expansion sleeve are cleanly cut, allowing for uniform expansion without tearing or misalignment.
Traceable Markings
Specifications, strength grades, and manufacturer codes are clearly marked on the product head or packaging, enabling full-process quality traceability.

Application Advantages
| Building Structure and Equipment Installation | Used to secure equipment and components-such as outdoor air conditioning units, heavy-duty shelving, piping supports, cable trays, and railings-to concrete columns, beams, floor slabs, and walls. In the base anchoring of long-span steel structures, Sleeve Expansion Hooks serve as post-installed anchor points, allowing for flexible positioning. |
| Municipal and Infrastructure | Used to install fall-prevention nets on the walls of manholes, utility vaults, and water wells; multiple expansion hooks are used per net assembly, ensuring the load-bearing capacity meets safety standard requirements. In bridge reinforcement projects, Sleeve Bolt Hooks are utilized to anchor full-coverage suspended scaffolding and safety cables. |
| Industrial Warehousing and Workshops | Used to mount storage racks, tool boards, small equipment accessories, and utility lines on warehouse and workshop walls. In high-altitude work scenarios, Expansion Sleeve Hooks can serve as temporary anchor points for safety lines. |
| Photovoltaics and New Energy | In photovoltaic projects, heavy-duty expansion hooks are used to secure mounting rails to concrete roofs or structural columns. |
