Description
Technical Overview
These M-series threaded fasteners secure structural frame assemblies that utilize V-slot and T-slot aluminium extrusions with a minimum profile slot width of 10mm. Their angled corner geometry lets you insert the components directly into the channel slots smoothly, which reduces friction and catching during manual placement compared to standard rectangular hardware. This profile enables precise positioning within the linear rail channel before you perform the final tightening.
Applications
Engineers and builders use these tee nuts during the assembly, reinforcement, and modification of modular aluminium framing networks. The smooth-transition edge profile suits multi-point framing assemblies where hardware must move freely along the internal extrusion channels prior to being secured into a fixed position.
Typical applications include mounting components, brackets, and structural plates onto linear rails in equipment such as 3D printers, CNC routers, laser engravers, robotics enclosures, and custom industrial workstations.

Maker Store Tips and Tricks
-
Ensure the extrusion channel is clear of debris or burrs before sliding the nuts into position.
-
Select the corresponding M3, M4, or M5 screw length carefully to ensure full thread engagement without bottoming out against the interior of the aluminium rail channel.
