T-Nuts
T Nuts are a versatile and reliable fastening solution designed to provide a strong threaded fixing point in wood composite panels plastics and soft metals. They are ideal where access to the rear of a panel is limited because bolts or machine screws can be installed securely from one side only.
T nuts are commonly used as a secure threaded insert solution within timber aluminium profiles and composite materials. They are frequently paired with adjustable feet to create stable levelling assemblies for machinery workbenches conveyor systems and industrial frames. When combined the T nut provides a strong internal fixing point while the adjustable foot allows precise height adjustment and compensation for uneven flooring making them ideal for manufacturing construction and workshop environments.
What is a T Nut?
T Nuts also known as Tee Nuts are internally threaded fasteners that are typically pressed or hammered into pre-drilled holes. A wide flange helps distribute load while prongs grip into the substrate to resist rotation and pull-out. When a bolt is tightened from the opposite side the T Nut is drawn firmly into place creating a durable fixing point.
Key Features:
- Internal machine thread for secure bolt fixing
- Pronged flange to resist rotation and pull-out
- Suitable for blind installations
- Allows repeated removal and refitting of bolts
- Distributes load across a wider surface area
Key Applications and Industries
T Nuts are widely used across manufacturing trade and DIY projects where a strong reusable thread is needed in softer materials. Common uses include furniture manufacturing joinery speaker cabinets gym equipment automotive interiors and exhibition stand systems.

Frequently Asked Questions
Where are T nuts?
T nuts are a popular type of fastener that is commonly used during furniture assembly, woodworking and metalworking. They are named after their shape, which loosely resembles the letter "T". A T nut has a flanged top with usually four prongs that are designed to grip into the surface of the material that they are applied to when tightened. Tee nuts are often constructed from stainless steel, as stainless steel T nuts offer excellent resistance to corrosion, durability and strength. They can be used for indoor and outdoor applications and be relied upon to provide a long term, stable and secure connection. Tee nuts are usually used together with threaded bolts or screws. T nuts are generally inserted into a pre-drilled hole on the material's surface. They are then tightened into the hole and the prongs on the nut will embed the nut firmly into the material. A bolt or screw with the appropriate thread size can then be inserted into the thread inside the T nut. Their primary purpose is for securely adding threads to surfaces.
What are the advantages of using T nuts?
T nuts are a widely used fastening product that provide a number of advantages to applications. They are capable of providing a strong and secure fastening due to their prongs, which grip into the surface they are tightened against. Tee nuts are also quite simple and fast to install. Since they are added to pre-drilled holes, inserting the T nut and tightening them takes little effort and time when compared to other fastening methods. Pronged t nuts are a versatile fastening solution that is effective for use in wood, metal, plastic and composite materials. This makes them suitable for many applications within furniture assembly, the automotive and industrial settings. Stainless steel t nuts offer excellent corrosion resistance and will perform well even in outdoor areas with high humidity and contact with the elements. Finally, T nuts are designed to sit flush with the surface of the material they are applied to. Once tightened they will rest flat against the application, providing a neat and aesthetically pleasing finish.
What are T nuts also known as?
T nuts might also be written as tee nuts. Some people might also describe them as wood insert nuts, as fastening wooden materials is one of their most common applications. Similarly, they might be called furniture insert nuts, due to their popular use in furniture assembly. Some customers may know them as threaded insert nuts, pronged nuts or pronged t nuts thanks to their design and shape. We sell premium grade stainless steel t nuts alongside a more affordable zinc plated metal t nut.
What thread sizes of T nuts do you offer?
We are proud to offer a wide range of T nuts with metric thread sizes ranging from M5 up to M10. Our top selling tee nuts are the m8 t nut and m10 t nuts. Customers also find m5 t nuts and m6 t nuts useful for their projects and applications. If you require a non-metric size of T nut or another size that isn't listed, let us know on our contact us page.
Can I use T nuts in wood?
Yes! T nuts are ideal for use in woodworking and this is one of their most common applications, along with furniture assembly. Simply insert the tee nuts into drilled holes of an appropriate size. Give them a gentle tap with a hammer to ensure that the T nut's prongs embed into the wooden surface to create a strong grip. Once the tee nut is in place you are able to thread bolts or screws through the T nut. This will provide a strong, long lasting joint.
Can I use T nuts for a climbing wall?
Yes, T nuts are commonly inserted into the backside of a climbing wall surface and used to attach bolt on climbing holds, such as handholds and footholds. They can be placed at strategic locations to create climbing routes and challenges for climbers. T nuts are able to provide a strong and secure attachment point for climbing holds. We recommend stainless steel T nuts for this application, to ensure the T nut has high stability, durability and strength to securely fasten the climbing holds into place. Additionally, the T nuts should be inspected regularly and a maintenance routine used to check for signs of wear and tear. This will ensure the climbing holds remain in good condition throughout their lifespan.
