Round Threaded Tube Inserts

Round Threaded Tube Inserts are a practical and reliable solution for adding threaded functionality to round tubes and pipes. Designed for use in a wide range of applications, these inserts are manufactured from high-quality materials such as LDPE plastic, polypropylene, nylon, or metal. Each insert features an internal M6 to M20 metal or plastic thread, allowing components such as adjustable feet, castor wheels, and threaded fixings to be securely attached.

These inserts are commonly used in furniture manufacturing, industrial frameworks, display systems, and heavy-duty applications where a threaded connection is required. Their ribbed exterior ensures a firm grip inside the tube, preventing movement over time. Available in a variety of sizes ranging from 19mm to 60mm Outside Diameter, our selection ensures a precise fit for different tube dimensions and wall thicknesses.

Why Choose Round Threaded Tube Inserts?

Round Threaded Tube Inserts provide a professional, secure, and stable connection for tubing-based structures. They are designed to evenly distribute weight, prevent floor damage, and increase the lifespan of furniture and equipment. The combination of a durable plastic or metal body with a strong internal thread ensures long-term performance, even under heavy loads.

By integrating these inserts, you can add functionality to tables, chairs, workbenches, and industrial racking systems without requiring additional modifications. Their easy-to-install design allows them to be tapped into place manually, making them a convenient choice for both DIY users and commercial manufacturers.

How to Select the Right Insert

Choosing the correct Round Threaded Tube Insert is crucial for ensuring a secure and stable fit. To make the right selection, consider the following:

• Tube Size: Measure the Outside diameter of your tube and then measure its Wall thickness. Subtract the Wall thickess value from the Outside diameter. This will give you the required "To Fit Tube" size.
• Thread Size: Ensure the thread (M6 to M20) is compatible with the component you intend to attach.
• Material: Choose plastic for lightweight applications or metal for heavy-duty use.
