Abstract

A metallic fastening member of a one piece configuration formed of a metal material includes a shaft portion (32) and a flange portion (33) extruding outwards from a first end of the shaft portion. The shaft portion (32) includes a relatively thin-walled portion (34) to be caulked at a second end opposite to the first end. A female thread (36) is formed at an inner peripheral face of the shaft portion excluding the portion to be caulked (34).
An annular groove (50) is formed at an outer peripheral face of the shaft portion (32) or at the inner peripheral face of the portion to be caulked (34), so that the shaft portion (32) has a partially thin wall. Since the wall of the shaft portion (32) is thinner at the annular groove (50), the metallic fastening member is fractured at that area to be separated into upper and lower pieces in the work of detaching the metallic fastening member from an object of fixation. Therefore, the metallic fastening member can be readily removed from the object of fixation to facilitate the recovery work for recycling purposes.
