It has a long, thin body and a flange at one end, resembling a T in profile. The flanges of T-nuts often have hooks or serrations on the prongs that sink into a wooden work piece, providing better retention.
Prongs dig into material to create a flush surface on the nut side
Bolt pulls the nut into the material
Hooks create a strong hold on a material
