Square Tube Inserts

Variations Of Square Tube Inserts

Square Inserts 10-38mm
These Square tube caps or Square tube ends as they are also widely known are an ideal choice for use as a functional or finishing insert as they can be used for a number of different uses such as to protect or to add grip to a Chair or piece of Furniture. Manufactured from an LDPE plastic these inserts have a solid finish and are a strong product for use with a range of products.
Square Inserts 40-76mm
These Square tube ends are made for square box sections over 76.2mm, this covers some of the biggest uses that you may come across. Each of these square tube caps comes with ribs on the side which help to prevent the insert from falling down or coming loose once it is in place, these inserts simply require a slight push once above its application for a tight, sturdy fitting.
Square Inserts 80-200mm
These square tube caps or Square tube ends as they are also known, are a popular ribbed box section insert due to their easy fitting ribs which allow them to sit tightly, flush at the end of the tube. These tube caps can provide a number of uses including functional and aesthetic uses which see them being used as feet or even finishing inserts regularly. These are cost effective inserts with a number of functional properties including being made from a durable LDPE plastic, something which provides a high quality product.
Square Angled Tube Inserts
Square tube ends with an angled base are an extremely popular choice for use with tubular chairs and are regularly used with desks that have tubular legs, however they can also commonly be used with Chairs. Available in a range of colours to suit rather than just a plain Black, we can ensure that we have the best possible choice for your specific application.
Domed Square Inserts
These Domed Square tube ends are a massively popular choice for use as a finishing insert, however they can also regularly be used with furniture to provide grip and stability where required. Domed inserts may be used with Chairs as replacement feet for use with angled surfaces as they have a domed surface with grip nodules which help to stop the Chair or piece of Furniture from slipping over.
Chromed Square Inserts
Being some of the newest products into our Square Tube Inserts range, these Chrome finish options are recommended for all uses where the aesthetic or look of an application is to be improved. Such finish is perfect for use with all metal tubes or box sections, fitting in with the style required of them in seconds. Also known as Tube Caps due to their capping properties, these can double up to prevent ingress and remove the need for internal protection against common issues such as rust.
Thin Head Square Inserts
Our Thin Square head inserts are a regularly used discrete option for the finishing of a tube or pipe, with the head of the insert sitting just below the flush of the end of the tube. Whilst providing a clean and functional finish, these are a cost effective insert costing similarly to our more standard inserts making them excellent value for money.
Square Threaded Inserts
Square Threaded Tube Fittings (Or plastic threaded tube inserts) are another widely used part that we keep in stock. They are often used with square tubes to provide a thread for external attachment, they fit perfectly into a square tube due to their ribs which allow them to sit firmly inside at all times, even with heavy usage. They work best when used with external attachment, however they can also be used to sit inside the tube to prevent ingress if necessary. Each insert has a number of variants and thread styles which ensures their effectiveness across a number of industries rather than just one or two, making these square threaded fittings an excellent all round choice. Square threaded tube ends are one of the most commonly used threaded inserts, commonly used with square box sections these inserts are easily placed inside of a tube before allowing an external component to be added. Fixings for feet come in all kinds of shapes and sizes, suited for all kinds of different fixing and product options, whether you have a tube, pole or wall area.
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.
Square Metal Inserts
Square metal tube inserts are a widely used insert solution for a number of different applications. One of the most common is for use with metal tubes where they can be tapped into to provide structural integrity and a threaded solution for the external fitting of parts such as machine feet which require a strong thread to work under heavy weight consistently. Metal inserts are made from steel as standard, this provides a high quality and strong insert that is easily able to absorb shock and withstand the pressure from heavy loads.

Our Square Tube Inserts, or Square Tube Caps For Box Sections as they are often referred to, are made from a selection of strong and reliable materials. These include LDPE Plastic & Aluminium Alloys.
