4 Prong Tee / T Nuts

T-Nuts are available in various diameters at competitive prices. Also known as 4-pronged t-nuts, or tee nuts. Used primarily in softer materials like wood, the nuts will provide an effective threaded insert.

Once the nuts are placed into a pre-drilled hole, the prongs around the flanged edge of the nut are tapped into the material securing the nut. Typically used on garden furniture, trailers, and flat-packed furniture. These nuts are available in A2 stainless steel and (BZP) bright zinc-plated steel.

What are T Nuts?

T Nuts, also known in the trade as t-nuts, 4-pronged t-nuts or tee nuts, is a nut with a flange that has four prongs around its outer edge.

What are T Nuts used for?

Generally used in woodworking and furniture making and once fitted provides a threaded insert ready for a bolt. Used in both softwood and hardwood, the pronged t-nuts are used by placing the threaded body into a pre-drilled hole. Tapping around the edge of the t-nut ensures the 4 prongs fix into the surface of a material which then allows the bolt or screw to be screwed into the nut. Drilling a pilot hole does help with the position of the t-nuts but ensure the nut has a firm hold before fixing a bolt to it.

What are T Nuts made from?

The 'T Nut' is manufactured from various materials and here are Fusion Fixings they are supplied in A2 stainless steel which offers a good level of corrosion resistant and bright zinc plated steel (BZP) which offers a mid-level resistance to corrosion.

A2 Stainless Steel

A2 grade stainless steel is also referred to as 304 or 18/8 steel, due to the alloy comprising of 18% chromium and 8% nickel. The higher level of chromium helps the alloy resist and prevent the spreading of corrosion. A2 stainless steel t-nuts are a good choice when a higher levels of corrosion resistance might be required.

Zinc Plated

Zinc plated passivation is a common finish on steel products and this due to its affordability and availability. Once applied, the layer of zinc provides a galvanised protection to the steel which helps to prevent oxidization. In the case of the tee nuts, the zinc plating is BZP, which is a bright zinc plating, that leaves a relatively thin layer of zinc on the surface. Whilst it does provide resistance to moisture, it will struggle to prevent rusting when used outside for longer periods.
