Heavy Duty Square Tube Inserts with M10 Metal Thread

Turn standard square tubing into adjustable furniture legs instantly.

Upgrade your furniture projects with our premium Square Tube Inserts, specifically designed to accept M10 adjustable screw-on feet. Proudly Made in Germany and stocked in the UK, these inserts combine precision engineering with heavy-duty durability.

Whether you are building industrial shelving, repairing school chairs, or fabricating custom metal frames, these inserts provide a robust, threaded anchor point. The high-quality Polyethylene (PE) body ensures a tight friction fit, while the embedded M10 metal thread offers superior strength compared to standard plastic threads.


Why Choose These Tube Inserts?

  • German Engineering: Manufactured to exacting standards in Germany for consistent quality and reliability.
  • Heavy-Duty Construction: Made from durable black Polyethylene (PE) plastic that resists wear, tear, and impact.
  • Strong Metal Core: Features a robust M10 metal thread embedded in the centre, providing a secure base for levelling feet and castors.
  • Secure Ribbed Fit: The multi-ribbed design allows for easy tapping into place while preventing the insert from falling out or wobbling over time.
  • Versatile Applications: Ideal for industrial shelving, metal desks, washing machine stands, school stacking chairs, and display stands.

IMPORTANT: How to Order the Correct Size

Please read this before purchasing to ensure a perfect fit.

To avoid ordering errors, you must measure the OUTER dimensions of your tube, not the hole inside.

  1. Measure the Outside: If your square tube measures 25mm x 25mm on the outside, you need the 25mm x 25mm insert.
  2. Check Wall Thickness: These inserts are designed for tubes with a wall thickness between 1.5mm and 2mm.
  3. Check Your Feet: Ensure the adjustable feet you plan to screw in have an M10 thread size.

Note: If your tube wall is thinner than 1.5mm, the fit may be loose. If it is thicker than 2mm, the insert may not fit inside.
