45 Series M8 Hidden Corner Bracket for T-Slot Profiles
This 90-degree hidden corner bracket creates a clean internal connection between 45 series T-slot or V-slot aluminum profiles. Its compact L-shaped body fits inside the frame corner, helping keep the outside surface clear while providing stable mechanical support.
The bracket is supplied with two M8 set screws. Silver and black finishes are available to match common profile colors. Installation uses standard tools and does not require welding, so the joint can be adjusted or removed during maintenance.
Key Features
- Designed for 45 series aluminum extrusion and T-slot framing.
- Inside-mounted design creates a neat, space-saving 90-degree joint.
- Zinc-alloy construction provides strength for industrial frame assembly.
- M8 threaded holes and two matching set screws support fast installation.
- Available in silver or black for different frame finishes.
- Suitable for machine frames, guards, workstations and 3D printer structures.
