T-Nuts with Spring Leaf
XAHV21 · XAHV23 · XAHV31
T-nuts with spring leaf feature a flexible spring leaf that holds the nut in position within the T-slot before tightening. The spring leaf design provides a wider contact surface than spring ball variants, offering more stable pre-tightening retention. Compatible with both EU and GB standard profiles.

Key Features
Spring Leaf Retention
The flexible spring leaf provides a wider contact surface than spring ball variants, offering more stable pre-tightening retention and reducing nut rotation during assembly.
EU & GB Profile Compatible
Compatible with both EU standard (308, 408, 4010/4510/5010) and GB standard (G408) profiles, providing versatility across different T-slot profile systems.
Stable Pre-Tightening Position
The spring leaf engages the slot walls to hold the nut firmly in position before tightening, preventing rotation and displacement during fastener installation.
Wide Contact Surface
The spring leaf design distributes load across a wider area compared to spring ball nuts, reducing stress concentration and improving durability in high-vibration applications.
Efficient Assembly
Pre-position multiple nuts along the slot before installing fasteners, enabling efficient batch assembly of brackets, panels, and accessories on aluminum profile frames.
Repositionable Design
Slide nuts to any position along the T-slot before tightening, enabling precise alignment of brackets, panels, and accessories without removing the fastener.
Typical Applications
Automated Machine Frames
Secure brackets, panels, and accessories to EU and GB profile machine frames with precise, adjustable positioning before final tightening.
Industrial Safety Guards
Mount safety guards and protective panels to profile frames in manufacturing environments where secure, vibration-resistant fastening is required.
Conveyor Systems
Fasten guide rails, sensor brackets, and structural accessories in profile conveyor and material handling systems with stable retention.
Modular Workstations
Attach and precisely position work surface components, monitor arms, and accessories on adjustable profile workstation frames.
Cleanroom Equipment
Use in cleanroom frames and laboratory benches where corrosion resistance and spring-retained positioning are required.
Control Panel Assembly
Mount control panels, displays, and instrumentation on profile frames with secure, repositionable fastening for easy adjustment.
