Stainless Steel L-SHAPED 2040 Profile Corner Outer Bracket
Product Summary
Product Name: Stainless Steel L-Shaped 2040 Profile Corner BracketPurpose: Connects 2040 aluminum extrusion profiles at a rigid 90° angle to build frames, enclosures, machines and structures.
Core Function:
Facilitates right-angle joints between two perpendicular 2040 (20 mm × 40 mm) aluminum profiles.
Provides mechanical strength and alignment for modular framing systems.
Typical Specifications
Compatibility
Designed for 2040 series aluminum extrusion profiles (20 mm × 40 mm cross-section).
Fits standard T-slot/V-slot profile systems used in industrial framing, robotics, CNC machines and DIY builds.
Material
Stainless Steel body (common grades used include AISI 304 or AISI 316 depending on supplier).
Stainless steel improves corrosion resistance over typical mild steel or aluminum brackets and is suitable for moist, chemical or outdoor environments.
Physical Dimensions (approximate & dependent on supplier)
Bracket leg lengths typically sized to accommodate material thickness and provide secure engagement inside the profile slot.
Often bracketing surfaces are sized similar to 2040 profile webface (~40 mm height on one side).
Thickness and deployed width vary by manufacturer. (Exact data sheet should be consulted for precise numbers.)
Fastening Interface
Pre-drilled or machined bolt holes matched to the extrusion slot hardware (often M5 screws and T-nuts, depending on profile system).
Hole centers and thread sizes align with standard profile fastening hardware.
Finish
Natural stainless steel (mill finish) or passivated for improved corrosion resistance.
Features
Structural and Mechanical
90° Right-Angle Joint: Provides robust structural corner connection for frame assembly.
High Strength: Stainless steel construction offers higher tensile strength and durability relative to aluminum alloy brackets — useful where higher load capacity or vibration resistance is desired.
Corrosion Resistance
Stainless steel resists rust and oxidation, ideal for humid, coastal, food processing, laboratory or outdoor applications.
Modular Assembly
Works with standard T-slot / V-slot extrusion hardware (T-nuts and socket cap screws).
Enables repeatable, adjustable, reconfigurable structural connections.
Installation
Bracket legs slip into extrusion slots and are tightened with bolts and nuts inside the profile channels.
Screws typically inserted from outside for secure fastening.
Typical Applications
Industrial Frames: Machine guards, enclosures, benches, automation assemblies.
CNC & 3D Printing: Rigid corner joints on printer or router frames.
Robotics & Automation: Structural support for robotic arms, conveyors and fixtures.
Custom Equipment: Workstations, shelving, fixtures requiring corrosion-resistant joints.
Performance Considerations
Load Capacity
Stainless steel brackets generally have higher static loading capacity than aluminum counterparts.
Actual performance depends on bracket geometry, thickness, screw grade and tightening torque.
Assembly Tips
Use matching T-nuts and screws sized for 2040 profile (usually M5 hardware).
Ensure perpendicular alignment during tightening for maximum rigidity.
