Description
Technical Overview
The 90 Degree 4 Hole Corner Bracket – 30 Series M8 6mm Tab is a die-cast aluminium right-angle fastening component with an enclosed box-section design for 30 Series aluminium extrusion systems. Unlike open two-hole brackets, it uses two M8 fixing points per arm – four in total – and a closed triangular profile that substantially increases rigidity and resistance to racking at corner joints.
The enclosed construction distributes clamping load more evenly across the joint, making it suited to frames carrying higher loads or subject to lateral forces. A plastic cover is included with each bracket, snapping onto the open back of the box section to give the finished corner a clean, closed appearance.
Applications
Use the 90 Degree 4 Hole Corner Bracket – 30 Series M8 6mm Tab to reinforce high-load or structurally critical corners in 30 Series aluminium framing. It suits machine frames, structural enclosures, industrial workstations, and equipment frames where a two-hole bracket does not provide sufficient resistance to lateral movement.
In a frame assembly, it pairs with Sliding T-Nut – 30 Series, 10 Pack and four M8 cap head bolts. For the 8mm tab version of the same bracket, the 90 Degree 4 Hole Corner Bracket – 30 Series M8, 8mm Tab is the direct alternative.

Maker Store Tips and Tricks
-
- Ensure the mating 30 Series profiles are cut square and fully seated in the bracket cavity before tightening any fasteners.
- Tighten the four M8 bolts in a diagonal sequence – snug all first, then torque to spec – to prevent uneven clamping and frame twist.
- The enclosed design self-squares the joint during assembly; confirm the 90 degree angle before final tightening.
- Snap the plastic cover onto the back of the box section after assembly to close the bracket cavity and give the corner a finished appearance.
- For high-vibration applications, apply a medium-strength thread locker to all four M8 bolts to maintain joint integrity.
