Looking for a threaded tube insert that can support heavy-duty feet? This threaded tube insert from our trusted RS PRO range easily fits into square-shaped tubing, making it simple for you to attach casters or feet to heavy equipment.


Inserting the threaded tube gives you an attachment point that's easy to install – all you need to do is tap it into place. The threaded grip holds the self-levelling castors or feet firmly in place once it's in the tube.


The reinforced black nylon outer body of the tube is durable and long-lasting, while the nickel-plated brass bush offers good resistance to corrosion. This makes the tube insert a good choice for heavy-duty use under weighty, bulky machinery without the risk of buckling.
