A tee nut has a stem portion and a flange portion which are integrally made by performing sheet metal processing using an iron sheet. The stem portion has a crimping-scheduled portion at an end opposite to the flange portion. The inner peripheral surface excluding the crimping-scheduled portion is formed with a female thread. The flange portion is provided with a plurality of pawls formed by inwardly crushing part of the outer peripheral edge of the flange portion from outside. The pawls satisfactorily performs the function of inhibiting rotation relative to an object to be fixed and yet they do not project so much and, furthermore, the pawls can be driven into the object concurrently with the crimping applied to the crimping-scheduled portion.
