A removable blind fastener comprising an anchor having anchor members each having a threaded outer surface and a retainer section, and an anchor drive mechanism comprising a shaft having a top portion with a threaded section. The retainer section has a periphery that extends beyond a periphery of the elongated body. The anchor in a closed configuration is inserted through a frontal face of a hole on a work piece such that the retainer sections are positioned behind a rear face of the hole. The anchor is then set in an open configuration and the shaft is placed irrotatably between the anchor elements. A head having internal threads is engaged to the threaded outer surface and the threaded section such that rotation of the head causes a retraction of the anchor till at least a part of the retainer sections abuts the rear face of the hole.
