What these M5 T-nuts do

The M5 T Nuts with Ball Bearing for 40 Series (10-Pack) are fastening components designed for secure, efficient attachment inside 4040 V-Slot and T-Slot aluminum extrusions. The built-in ball bearing helps the T-nut insert smoothly, align itself in the slot, and hold firmly once tightened.

These M5 T-nuts provide a strong, slip-resistant connection for high-load builds that use 40 Series aluminum extrusion. The design is practical for both structural assemblies and motion-based systems where reliable fastening matters.

Key features and fastening benefits

• High-strength carbon steel construction supports durable fastening in demanding assemblies.
• Zinc-plated finish helps improve corrosion resistance and long-term durability.
• M5 thread size matches standard M5 screws and bolts.
• Ball bearing mechanism adds self-aligning and anti-slip properties for a secure connection.
• Drop-in and roll-in design slides easily into compatible 8mm slots on 40 Series extrusion.
• Firm holding power helps the T-nut lock in place when tightened to reduce loosening over time.

Where these ball bearing T-nuts are used

Heavy-duty machine frames

These fasteners are well suited to securing brackets, plates, and other components in machine frame assemblies built from 40 Series extrusion. The strong grip and slip-resistant fit are useful in builds that carry higher loads.

Automation and robotics assemblies

The self-aligning design makes these T-nuts a practical choice for mounting sensors, motion systems, and industrial components in automated equipment and robotic builds. Smooth insertion also helps when making adjustments during assembly.

DIY and modular extrusion projects

For makers, workshop fixtures, and modular frame projects, these M5 T-nuts simplify the process of adding accessories and structural elements to aluminum extrusion frameworks. The result is a secure fit without complicated installation.
