Threaded Insert Nuts

Threaded inserts for wood

A range of threaded inserts for wood, available in a selection of sizes at competitive prices.  Threaded insert nuts used in applications where a bolt or screw with a metric thread needs to be screwed into wood to enable components to be fixed together. 

Available as a ‘type D’ or ‘type E’ insert nut, with the 'type D' nut having a small flange at the top. This allows the nut to sit flush to the material surface, while the ‘type E’ insert nut doesn’t have the flange and can be screwed deeper into the material if needed.

Widely used in furniture assembly to attach various materials together. The nut provides a strong threaded socket that acts as an anchor within a material for a bolt or screw to be fitted.

Available in various diameters and lengths with bulk discounts available.

What are threaded insert nuts?

Threaded insert nuts also known as threaded inserts, are thick-walled tubes which have a screw thread internally and are also threaded externally. The external thread holds the nut in place within the material while the internal thread is used by the bolt or screw. Some threaded inserts have a small flange at the top and these are designed to sit flush to the top of the material. Others are missing the flange which allows them to be screwed deeper into the material if needed.

What are threaded insert nuts used for?

Threaded inserts are small fasteners used to assemble and attach two materials together. The threaded insert nut is placed within the target material. They are usually installed by drilling a pilot hole and then screwing the insert in place. The bolt or screw is then fixed through the material and into the threaded nut, locking the two materials together.

What are threaded insert nuts made from?

Threaded inserts can be manufactured in various materials and here at Fusion Fixings they come in zinc-plated steel for a medium level of corrosion. Being zinc-plated they can have a yellow appearance or more of a bright zinc appearance. This is due to the passivation process, but both offer the same level of corrosion resistance.
