Key Features
Hammer Head Design
The distinctive hammer head profile allows insertion at any point along the T-slot by rotating 90°, eliminating the need to slide the nut in from the profile end.
GB & EU Profile Compatible
Available for both GB standard (G306, G408) and EU standard (206, 308, 408, 4010/4510/5010) profiles, covering the most common industrial T-slot systems worldwide.
High Load Capacity
Steel variants (XAHC22, XAHC23) provide superior tensile and shear strength for heavy-duty structural connections in machine frames and industrial enclosures.
Multiple Code Options
Four code variants (XAHC21–XAHC31) cover zinc alloy and steel materials in silver and black finishes, allowing selection based on load requirements and aesthetic preference.
Precise Dimensional Tolerances
CNC-machined to tight tolerances for consistent fit across all compatible profiles, ensuring repeatable assembly quality in production environments.
No Disassembly Required
Insert at any position along the slot during or after frame assembly, significantly reducing installation time compared to traditional slide-in T-nuts.
Typical Applications
Automated Machine Frames
Secure brackets, panels, and accessories to CNC machine frames, robot cells, and automated assembly lines where reliable, repositionable fastening is required.
Industrial Safety Guards
Mount safety guards, protective covers, and enclosure panels to aluminum profile frames in manufacturing environments.
Conveyor & Material Handling
Fasten guide rails, sensor brackets, and structural members in conveyor systems and material handling equipment.
Workstations & Ergonomic Benches
Attach work surface components, monitor arms, and accessories to adjustable-height workstations and ergonomic bench frames.
Exhibition & Display Structures
Connect panels, lighting fixtures, and display components to modular aluminum profile exhibition stands and trade show booths.
Cleanroom & Laboratory Equipment
Use anodized variants in cleanroom frames and laboratory benches where corrosion resistance and hygiene standards are required.
