Square Steel Tube Ends

Threaded Square Tube Inserts, or simply Square Thread Inserts, are used to protect assemblies from the share edge of the tube and provide an aesthetically pleasing appearance. The threaded tube inserts have an internal thread that can accommodate components, such as leveling feet, tilt glides or castors.

Our Square Metal Threaded Inserts are made from High Density Polyethylene (HDPE) with Zinc Plated Steel threaded insert. Ideal for adjustable leveling mounts and feet, and ribbed to accommodate multiple gauges. They are blank in appearance.

If you're looking for something more robust, perhaps view our Square Heavy Duty Threaded Inserts. Made from glass-filled black Nylon with a Brass threaded insert. These threaded tubing inserts can be used indoors and outdoors - so are highly versatile. The high load rating is a great choice for machinery use.

Perhaps try our Plastic Threaded Tubing Inserts - made from Nylon, and available in a choice of Black and Natural colors. These are suitable for use with adjustable feet and tilt glides.

If a single-material option is your preference, our All-Metal Square Tube Inserts might be just right for your application. This thread steel tube option is made from Zinc Plated Steel. The metal ribs lock on to the inside of a square tube providing a tough and secure assembly.

Our square thread insert range is available in a selection of styles, materials and size options to suit your every need.
