Inserts for round and square tubes, which have been designed to solve issues related to the forming of threaded holes inside tubes – by replacing the traditional process of welding nuts yet providing a secure and tight fitting – have now been added to Fixi’s wide range.

Made of special steel, Fixi tube inserts guarantee high-tensile strengths after application thanks to the anchoring function of the spring crowns, which expand once inside the tube, without altering the shape and design of the outside.

The range of inserts is available in different sizes to fit all types of tubes, ranging from 11.8mm to 61.5mm for inside diameters of round tubes and from 15.7mm x 15.7mm to 48.8mm x 48.8mm for inside dimensions of square tubes. The thread sizes range from M6 to M10, sufficient for any structural requirement.

A key feature of the range is the easy and quick fitting by pressure installation both manually or with automated machines. For both round and square tubes the insert is available with or without head. The flanged version, in addition to having an aesthetic function by closing the end of the tube, allows the insert to work even under pressure, so it is ideal for applications on table and chair legs. There is also a special ‘simple’ version to fit flanged insert for swivel wheels.

Fixi Srl has widened its range of products to become a reference point for new industries thanks to these new tube inserts. As well as being used in the furniture industry in the production of tables, chairs, sofas, beds and lamps, the inserts can be used in products with a tubular structure such as gym equipment, trolleys and strollers. The inserts can also be used in signage and construction structures.
