Threaded Spring Tube Inserts

Threaded Spring Tube Inserts are a specialised heavy-duty fitting designed to provide a secure, threaded connection within metal tubes, pipes, or box sections. Manufactured from high-quality spring steel, these inserts utilise an expanding spring mechanism that ensures a firm grip once installed, preventing movement or loosening over time. This makes them a highly durable and reliable choice for a range of demanding applications, including machinery, industrial frameworks, and structural supports. Available in round and square profiles, as well as a glide version for smooth movement, these inserts offer versatility for various installations.

How to Measure for the Correct Insert

Selecting the correct Threaded Spring Tube Insert requires careful measurement to ensure a secure and accurate fit. To determine the appropriate size:

• Measure the outside diameter of your tube.
• Measure the wall thickness of the tube.
• Subtract the wall thickness from the outside diameter to determine the internal diameter (this is the "To Fit Tube" size).
• Match this measurement to the available product range to ensure a proper fit.

If you require assistance in selecting the right size, our team is happy to help. Business customers can also request a free sample to test the fit before purchase.

Round Threaded Spring Tube Inserts

Round Threaded Spring Tube Inserts are designed for circular tubes and provide a strong and reliable threaded connection. The expanding spring feature ensures the insert remains firmly in place, making them ideal for machinery, heavy-duty racking, and industrial frameworks. These inserts are commonly used to attach adjustable feet, castors, or other threaded components to tubular structures.

Square Threaded Spring Tube Inserts

Square Threaded Spring Tube Inserts are specifically designed for use with box-section tubing. Unlike standard threaded inserts, the expanding spring mechanism provides a superior hold, ensuring the insert does not shift under load. These are commonly used in structural frameworks, scaffolding, and furniture manufacturing.

Metal Spring Insert Glides

Metal Spring Insert Glides are a unique variant designed to act as a base, offering both threaded functionality and smooth movement. These inserts are perfect for applications where stability and mobility are required, such as furniture bases, conveyor systems, or heavy-duty equipment that needs to be repositioned regularly.

Common Applications

• Providing a secure threaded connection inside metal tubes and box sections.
• Attaching adjustable feet, castors, or other threaded fittings to industrial frameworks.
• Enhancing stability in machinery, furniture, and heavy-duty racking systems.
• Ensuring non-slip, durable fittings in demanding environments.
• Allowing smooth gliding movement in applications that require repositioning.
