A Tee nut, also known as a blind nut or a T-nut, is a type of fastener used in various industries for securing objects to materials that are not easily accessible from the backside. It is a threaded insert with a flat base in the shape of a T, hence the name. Tee nuts are commonly made from steel, stainless steel, or brass, and are designed for use with bolts or screws. 

The Tee nut features a threaded barrel that allows it to be driven into a pre-drilled hole, creating a secure and permanent connection. Its unique design enables it to be installed flush with the material surface, providing a clean and professional finish. This makes it an ideal choice for applications where aesthetics and functionality are equally important. 

Tee nuts are extensively used in furniture manufacturing, cabinetry, woodworking, and assembly operations. They are highly versatile and can be utilized in both industrial and DIY projects. The wide range of available sizes and thread options allows for compatibility with various materials and applications.
