T-Nuts with Spring Ball
XAHA21 · XAHA23 · XAHA31
T-nuts with spring ball are designed for EU standard T-slot profiles. The spring-loaded ball retains the nut in the slot before tightening, preventing displacement during assembly. These nuts must be inserted from the profile end and are ideal for pre-assembly installation.

Key Features
Spring Ball Retention
The spring-loaded ball holds the nut securely in the T-slot before fastener tightening, preventing displacement during assembly and reducing dropped-nut incidents.
EU Profile Compatible
Designed for EU standard T-slot profiles from 20 to 50 series, covering 206, 308, 408, and 4010/4510/5010 profile systems used in European and global industrial applications.
End-Feed Installation
Slide into the T-slot from the profile end for pre-assembly installation. The spring ball engages the slot walls to hold position until the fastener is tightened.
Precise Dimensional Tolerances
Machined to tight tolerances for consistent engagement with EU profile T-slots, ensuring reliable clamping force and repeatable assembly quality across all series.
Multiple Material Options
Available in zinc alloy (XAHA21, XAHA31) and steel (XAHA23) variants to match load requirements. Steel variants provide higher tensile strength for heavy-duty 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.
Typical Applications
Pre-Assembly Frame Construction
Install multiple T-nuts along EU profile slots before assembling the frame, enabling efficient batch fastening of brackets and structural members.
Automated Machine Frames
Secure brackets, panels, and accessories to EU profile machine frames in CNC machining centers, robot cells, and automated assembly lines.
Industrial Safety Guards
Mount safety guards and protective panels to EU profile frames in manufacturing environments where secure, vibration-resistant fastening is required.
Conveyor Systems
Fasten guide rails, sensor brackets, and structural accessories in EU profile conveyor and material handling systems.
Modular Workstations
Attach work surface components, monitor arms, and accessories to adjustable EU profile workstation frames with secure spring-retained fastening.
Cleanroom Equipment
Use in cleanroom frames and laboratory benches where corrosion resistance and dimensional accuracy are required.
