ABSTRACT:
A Tee-nut with flareable portion comprises a flange head, a plurality of prongs extending from the flange head, and a hollow barrel extending from the flange head. The hollow barrel has an internally threaded portion provided at one end of the barrel connecting to the flange head, and an enlarged flareable portion extending from the internally threaded portion and provided at a free end of the barrel. The end of the enlarged flareable portion is radiussed inwardly so as to form an end opening having a diameter which reduced in relation to the diameter of the flareable portion to facilitate insertion into a hole in a workpiece. The present invention further discloses a workpiece fitted with such a Tee-nut.
