Secure-Grip Expansion Hook
Products Description
The Secure-Grip Expansion Hook is a mechanical expansion anchor that uses a tightening process to cause the cone to push the expansion sleeve radially, creating strong friction and engagement with the substrate.
Its core structure includes:
A high-strength screw body
A multi-segment expansion sleeve
A precision-machined conical expansion core
An engineering-grade bent hook end
This structural combination allows the expansion hook to maintain excellent stability under tension, shear, and combined load conditions, making it particularly suitable for fixing requirements involving suspension or exposed connections.
Core Product Advantages
High Anchoring Reliability
Through a multi-point contact expansion structure design, the Expansion Fastener Hook forms a uniform force distribution within the hole wall, reducing the risk of localized stress concentration and improving overall anchoring safety.
Strong Anti-Loosening Capability
The mechanical locking method does not rely on adhesives or chemical reactions, maintaining stable fixation even in environments with vibration or temperature changes, making Hollow Wall Expansion Hook suitable for long-term operating engineering systems.
Efficient Installation
No complex tools or additional procedures are required; installation can be completed quickly after standard drilling, facilitating on-site construction pace control and optimizing labor costs.
Versatility and Compatibility
Adaptable to various substrates and structural forms, suitable for common building and industrial standards in different countries and regions.
Core Processing Flow
Integrated Molding: Using a high-speed precision cold heading machine, one end of the wire is pressed into a wedge-shaped mandrel and expansion tube using a special mold. Grooving of the expansion tube is completed simultaneously, ensuring the coaxiality and expansion consistency of the expansion structure.
Hook Bending: A CNC bending machine is used to bend the other end of the wire, controlling the Concrete Expansion Hook opening size, arc, and bending angle to ensure a flat load-bearing surface and no cracks at the bend.
Threading: A thread rolling machine is used to roll the mandrel to form standard threads. The thread rolling process does not cut the material, preserving the original strength of the thread.
Surface Treatment: Depending on the material and customer requirements, surface treatments such as galvanizing, passivation, hot-dip galvanizing, and phosphating are performed. After treatment, the surface is cleaned and dried to ensure no residual agents and a uniform coating.
