Description
The T-Slot Nut is a slide-in fastening element for aluminium profile systems, designed to create a secure internal threaded connection inside the profile slot. It is inserted from the end of the profile and guided by its shaped body so that it aligns correctly in the T-slot. This makes it suitable for rigid frame assembly, brackets, machine guards, fixtures and other modular aluminium-profile constructions.
The product is available for 20, 30, 40 and 45 profile slot systems, with several internal thread options depending on the selected size. Use the dimensional data below to match the nut to the profile series and required screw thread.

Key Features
- Slide-in installation: Loads from the open end of the aluminium profile and runs inside the profile slot.
- Self-aligning geometry: The shaped projection helps position the nut correctly inside the T-slot during assembly.
- Multiple profile series: Available for 20, 30, 40 and 45 aluminium-profile systems.
- Multiple thread options: Depending on size, versions are available from M3 up to M8.
- Rigid fastening point: Provides an internal threaded connection for brackets, plates, accessories and structural joints.
Selection and Compatibility
Select the T-slot nut first according to the aluminium profile series, then choose the required internal metric thread. The table above shows the available thread range for each nut family together with the principal dimensions used for fit and positioning.
Because this is a slide-in type, installation is normally performed before the profile end is closed or obstructed by another component. For assemblies that require insertion from the slot face after the frame is already built, a different T-nut style may be more suitable.
Typical Applications
T-slot nuts are commonly used for assembling CNC machine frames, router structures, worktables, guards, mounting plates, brackets, sensor supports and general modular aluminium-profile constructions.

Installation Notes
Insert the nut from the open end of the aluminium profile, slide it to the required position and align the threaded hole with the component being fastened. Install the corresponding metric screw and tighten the joint according to the requirements of the assembled structure. Confirm that the selected nut size matches the profile slot series before assembly.
