The nut has a T-shaped head that is essential to the way that it connects into the profile. Once pushed into the profile vertically, it gets turned horizontal/sideways in order to lock in. Its primary function is allowing screw or bolt elements to be fastened into the nut and be fixed to their required positions. This product is an t nut, used for fastening purposes on 45mm Profile extrusion. This nut can be inserted directly at the assembly point. Therefore, the connection is incredibly efficient.
