Description
Technical Overview
The 90 degree 2 Hole Economy Corner Bracket – 30 Series M8 is a lightweight cast aluminium bracket for 90-degree corner joints in 30 series T-slot aluminium extrusion frames. Also the economy option in the M8 cast corner bracket range, it delivers reliable corner reinforcement at just 0.018 kg – making it well suited to assemblies where many corner points are bracketed and overall frame weight or per-unit cost is a consideration.
Within a T-slot frame, one M8 fixing point per arm clamps adjoining profiles firmly into the slot channel. Furthermore, the cast aluminium construction maintains dimensional accuracy at the joint, helping preserve perpendicular alignment across modular frames over time.
Applications
The 90 degree 2 Hole Economy Corner Bracket – 30 Series M8 reinforces corner joints in 30 series aluminium extrusion assemblies. For example, it suits workstation frames, shelving structures, light machine enclosures, laboratory rigs, and custom jigs – in particular builds where many corner points need bracketing and a lower-mass M8 option helps manage frame weight or material cost.
In a frame assembly, it pairs with 30 series sliding T-slot nuts and M8 cap head bolts for straightforward assembly and later repositioning along the profile. For joints carrying heavier sustained loads, the 2 Hole Corner Bracket – 30 Series, M8 is the higher-mass alternative at the same M8 fixing size.

Maker Store Tips and Tricks
-
- Cut mating profiles square and seat them fully in the bracket before snugging any bolts – a gap at the joint face reduces clamping efficiency.
- Snug M8 fasteners lightly, verify 90-degree alignment, then fully tighten to avoid introducing twist into the frame.
- In high-vibration applications, use a medium-strength thread locker on M8 bolts to maintain joint integrity over time.
- Recheck bolt tightness after the first load cycles, particularly in frames carrying dynamic or impact loads.
