Key Features
Roll-in Installation
Tilt and roll the nut into the T-slot at any position along the profile — no end access required. Add fastening points to assembled frames without disassembly.
EU Profile Compatible
Designed for EU standard T-slot profiles from 20 to 50 series (206, 308, 408, 4010/4510/5010), covering the most widely used EU profile dimensions in industrial applications.
Precise Fit
Machined to tight dimensional tolerances for consistent engagement with EU profile T-slots, ensuring reliable clamping force and repeatable assembly quality.
Compact Profile
Low-profile design fits flush within the T-slot channel, maintaining a clean frame exterior without protruding hardware.
Multiple Material Options
Available in zinc alloy (XAHD21, XAHD31) and steel (XAHD23) variants to match load requirements. Steel variants provide higher tensile strength for heavy-duty applications.
Fast Post-Assembly Addition
Add fastening points to completed EU profile frames without disassembly, significantly reducing modification time in production and field service environments.
