Abstract
Disclosed herein is a Tee nut which can form a hole in a work piece with no problem by driving of the Tee nut itself, without previously forming a hole in the work piece. A closure member is engaged in a hollow shaft portion, to divide a portion to be caulked from a female threading carrier portion. A punched-out portion resulting from a hole which is formed by driving of a Tee nut itself is prevented by the closure member from reaching the female threading carrier portion, so that the punched-out portion can be discharged at the same time by extruding the closure member.
