Rectangular Threaded Tube Inserts

Our Rectangular Threaded Tube Inserts are designed to provide a secure and functional solution for inserting threaded components into rectangular box sections, tubes, or pipes. Manufactured from durable materials such as LDPE plastic, polypropylene, and aluminium, these inserts feature an integrated metal thread, allowing for the attachment of components such as adjustable feet, castor wheels, and levelling glides. Their ribbed exterior ensures a tight and stable fit, making them ideal for both light and heavy-duty applications.

Available in a range of sizes with standard M8 to M10 thread options, our inserts offer an effective way to enhance the functionality of rectangular tubing, commonly used in furniture, industrial equipment, and construction applications.

How to Measure for the Correct Size

Choosing the right Rectangular Threaded Tube Insert requires accurate measurements of your tubing. Follow these steps to ensure a proper fit:

• Measure the Outside Dimensions (OD): Use a calliper or ruler to measure the outermost width of your tube.
• Measure the Wall Thickness: Use the same tool to measure the thickness of the tube wall.
• Calculate the 'To Fit Tube' Size: Subtract the wall thickness from the outside diameter. This value represents the internal diameter of your tube.
• Match the Size: Compare your calculated size to our available product range to find a suitable insert.
