If you’re searching for threaded tube inserts, plastic tube inserts, ribbed threaded inserts, or square tube end caps, this new range offers an economical solution for everyday fabrication projects.

What Are ECO Threaded Tube Inserts?

ECO threaded tube inserts fit securely inside square or round tubing to create a strong threaded fixing point for adjustable feet, castors, bolts, and levelling systems.

Each insert uses a ribbed outer body to grip the inside of the tube and improve retention during use. The integrated metal thread provides a durable mounting point for industrial and commercial applications.

Manufacturers and fabricators commonly use threaded tube inserts for:

• Industrial furniture
• Steel fabrication projects
• Warehouse equipment
• Machine frames
• Gym equipment
• Display systems
• Workbenches and workstations
• Handrails and barriers
• Retail fixtures
• Conveyor systems

The ECO range gives customers a practical alternative to premium inserts without sacrificing functionality.

Why Choose Our ECO Tube Inserts?

• Reduce Manufacturing Costs: Lower your component costs without compromising on usability or installation performance.
• Achieve a Secure Tube Fit: The ribbed body grips the internal tube wall securely to help minimise movement.
• Choose From Popular Tube Sizes: We stock a wide range of square and round tube inserts to suit common steel tubing dimensions.
• Select M8 or M10 Thread Options: Our threaded inserts support both M8 and M10 fixings for flexible installation.
• Match Different Wall Thicknesses: We offer multiple wall thickness options to help ensure compatibility with your tubing.
