Male-Female Combined Aluminium Undercut Anchor Bracket

The Male-Female Combined Aluminium Undercut Anchor Bracket is a concealed mechanical fixing solution designed for natural stone facade and architectural cladding systems. Compared with conventional ear-type(C-typed) undercut anchor brackets, its interlocking male-female structure provides multiple mechanical connection points, creating a more stable connection between the stone panel and the supporting subframe.

The system combines a compact aluminum bracket design with adjustable positioning and mechanical interlocking, making it suitable for facade projects where stable panel connection, installation adjustment and reliable load transfer are important.

Three-Part Undercut Anchor Assembly

The complete male-female combined undercut anchor bracket typically consists of three main components:

1. Main Support Bracket

The main bracket is the larger component of the assembly and is installed on the supporting steel angle or facade subframe.

It is normally secured with hexagon socket screws. A serrated anti-slip washer can be placed between the bracket and the steel angle. The serrated surfaces engage with the corresponding grooves around the fixing hole, helping resist movement and improve the stability of the bolted connection.

The support bracket can be manufactured in different widths and sizes according to project requirements.

2. Male-Female Interlocking Bracket

The secondary bracket consists of two matching aluminum components with complementary profiles. The two pieces mechanically engage with each other, creating an interlocking connection rather than relying only on a single screw connection.

This male-female configuration provides multiple contact surfaces and helps keep the bracket assembly securely engaged during installation and service.

The secondary bracket is connected to the main support bracket with a hexagon socket screw and is attached to the rear of the stone panel through an undercut anchor bolt.

3. Undercut Anchor Bolt

The undercut anchor bolt is installed into a specially prepared hole on the rear of the stone panel and provides the concealed mechanical connection between the panel and the bracket assembly.

For this system, an M8 impact-set undercut anchor bolt is commonly used. The appropriate anchor type and embedment depth should be selected according to the panel thickness, material, required load capacity and the technical specifications of the anchor.

Adjustable Top Screw for Panel Alignment

The male-female combined bracket features an adjustment screw at the top of the main bracket.

This screw can be used to make fine adjustments to the panel position and alignment during installation, helping installers achieve a more accurate and uniform facade surface.

This adjustment function is particularly useful when precise panel alignment is required across a large facade area.

Enhanced Connection Stability

Compared with a conventional C-Typed(ear-type) undercut anchor bracket, the male-female design uses a more developed mechanical interlocking structure with additional contact and connection points.

This configuration can provide:

● More stable mechanical engagement
● Better resistance to relative movement within the bracket assembly
● More flexible installation adjustment
● Higher potential load capacity depending on the bracket size and system configuration

For applications requiring higher load capacity, a larger or wider main support bracket can be selected according to the stone panel size, weight and project requirements.

Because this system contains more components and uses a more complex interlocking structure than a basic ear-type bracket, its manufacturing cost is generally higher.

Key Features

● Concealed rear fixing for stone facade systems
● Aluminum alloy bracket construction
● Male-female mechanical interlocking design
● Adjustable top screw for panel alignment
● Serrated anti-slip washer for improved connection stability
● Commonly configured with M8 impact-set undercut anchors
● Available in different bracket sizes and configurations
● Suitable for customized stone facade fixing systems


Typical Applications

The Male-Female Combined Aluminium Undercut Anchor Bracket is suitable for natural stone facade, granite, marble and architectural cladding applications where concealed rear fixing and adjustable panel positioning are required.

Undercut anchor facade systems are commonly used to connect stone panels to supporting brackets and subframes while keeping the mechanical fixing hidden behind the cladding surface.

The appropriate bracket size, anchor type, embedment depth and fixing configuration should be selected according to the panel thickness, panel dimensions, weight, support conditions and project-specific structural requirements.
