Threaded Spring Inserts

Our Spring Threaded Inserts & Steel Tube Connectors are manufactured to meet strict requirements and performance levels, ensuring a reliable solution. Produced from a durable Spring Steel these inserts are recommended to prevent the need for advanced and/or expensive drilling methods such as flow-drilling where a thread or object is added to a tube. Suited towards metal tubes or box sections these Spring Inserts are able to cope with a large amount of weight and tension, with the 'spring' type ribs expanding even further as the weight is increased. Installed by hand using a mallet or hammer these require a firm hit for a long term fitting to your tube or appliance, offering ideal properties for a heavy duty piece of equipment or machinery. We also offer Steel Tube Connectors which are suggested for the connection of two round tubes, joined by a male thread or component.

Variations Of Threaded Spring Inserts

Round Spring Inserts
Our round spring steel threaded tubes inserts are a widely used part that slots up inside of a tube or box section. These inserts are manufactured from a spring steel which releases on itself once pushed up inside of the tube, holding it firmly in place and preventing any form of movement. These threaded spring inserts also allow for the external addition of threaded components due to them coming with an in-built sturdy thread which comes in sizes m6-12.
Square Spring Inserts
Our spring steel threaded inserts are manufactured from a specialist spring steel, this is what gives these spring inserts their 'spring back' properties which is what holds them in place inside of the tube or box section. As well as providing structural integrity, these inserts are able to provide a thread for the external attachment of components such as our leveling feet which could simply be screwed into place.
Threaded Tube Connectors
Our threaded tube connectors or spring steel threaded tube connectors are a popular part inside a number of industries as they allow for an easy solution to attach two tubes. These connectors have been specifically designed to hold themselves in place with a springing steel exterior whilst their thread allows for the attachment of other tubes or threaded components.
