Expansion Anchor With Hook End
Products Description
The Expansion Anchor with Hook End is a mechanical anchoring product. Its core operating principle involves the radial expansion of the expansion sleeve-triggered by screwing in or tensioning the threaded rod-which creates a friction-based lock against the borehole wall, thereby ensuring reliable anchorage.
Key product features include:
1. Integrated Suspension Design
The product features a "Hook End" design, allowing for the direct suspension of:
Pipe and conduit supports
Lighting fixtures
Electrical enclosures
Industrial tools
Lifting and rigging accessories
Architectural decorative elements
This eliminates the need for additional mounting hardware, thereby improving installation efficiency.
2. Stable Mechanical Locking
The expansion mechanism deploys progressively during installation, creating a secure connection between the anchor and the base material, making it suitable for long-term, permanent fixing applications.
Production Process and Manufacturing Advantages
Precision Cold Forging and Forming
High-tonnage presses form the expansion sleeve and Hook Sleeve Anchor-end blanks, preserving material grain flow and enhancing structural integrity.
01
Machining
CNC turning and milling are used to machine threads and tapered surfaces, ensuring dimensional accuracy and superior surface finish.
02
Heat Treatment and Surface Protection
Controlled quenching and tempering optimize mechanical properties, followed by multi-layer plating or passivation.
03
Assembly and Pre-tightening
Automated assembly of screws and sleeves, accompanied by torque and expansion testing.
04
Rigorous Quality Control
Includes pull-out tests, salt spray tests, metallographic analysis, and full-dimensional inspection before packaging and shipment.
05
Main function: Build a multi-dimensional load support network
Axial suspension of heavy loads
Provide vertical upward tensile support for air conditioning units, fire ducts, bridges, etc., on the ceiling, and safely conduct the load to the main structure of the building.
Mechanical limitation of lateral displacement
The physical blocking properties of the Sleeve Expansion Hook end are used to fix and prevent the cable or pipe from moving laterally when subjected to external force or thermal expansion and contraction.
Disassembly-free quick-mount node
In situations where regular maintenance or hanging objects need to be moved (such as industrial lighting fixtures, temporary safety cables), the Sleeve Bolt Hook end provides a flexible interface that can be quickly removed and hung without tools.
Detailed View: Key Engineering Features
Cone Precision
The taper angle and surface finish of the conical core directly affect the uniformity of the expansion casing's radial expansion; precision machining ensures a precise fit between the cone and the casing.
01
Casing Segment Quality
Longitudinal slots are free of burrs and cracks, featuring radiused transitions at the slot ends to ensure uniform opening during expansion and eliminate the risk of fracture due to stress concentration.
02
Hook Bend Integrity
The bent section is free of cold-bending cracks and wrinkles, with a flat load-bearing surface to ensure even load distribution on the suspended Through Bolt Hook Anchor.
03
Thread Precision
Rolled threads feature a complete profile and smooth engagement, with clearly marked and traceable strength grade specifications.
04
Surface Treatment Uniformity
The coating offers uniform thickness and strong adhesion, passing salt spray tests with no exposed base material or blistering.
