Description
Technical Overview
The 30 Series – 90 degree 4 Hole L Bracket M6 is a right-angle bracket for modular aluminium T-slot framing systems. Its L-shaped body includes four mounting holes that accept standard M6 fasteners and T-nuts. As a result, it creates a rigid mechanical interface that joins two structural profiles securely at a perpendicular angle.
Within a modular framing system, the bracket acts as a structural joint that maintains alignment and stability between connected members. It also distributes fastening points across both sides of the corner, which improves load transfer and reduces movement or twisting. Builders commonly use it in machine frames, enclosures, and workstation assemblies that need repeatable, adjustable connections.
Applications
The 30 Series – 90 degree 4 Hole L Bracket M6 connects perpendicular members across modular aluminium extrusion assemblies. For example, builders use it in CNC machine frames, 3D printer enclosures, robotic structures, and industrial workstations. It also suits projects that need precise alignment between profiles, with flexibility to adjust or reconfigure the frame.
In mechanical assemblies, the bracket reinforces corners to resist twisting and lateral loads. It pairs with 30 series sliding T-slot nuts and M6 cap head bolts to lock aluminium profiles in position. For lighter builds, the 30 Series 2 Hole L Bracket M6 offers a smaller option with the same slot compatibility.

Maker Store Tips and Tricks
- Load T-nuts into the extrusion slots before bringing the bracket into position — slide-in T-nuts must be inserted from the profile end before end access closes.
- Finger-tighten all four M6 bolts first, confirm 90-degree alignment between profiles using a machinist square, then fully tighten in a diagonal sequence.
- Use this bracket in pairs — one bracket per face of the corner — for maximum resistance to racking loads on larger or heavily loaded frames.
- The flat L profile sits flush against both profile faces; check clearance if panels or covers will be mounted on the same slot face.
- For higher-rigidity requirements, consider a cast enclosed corner bracket, which provides additional web stiffness that this flat-plate style does not.
