    摘要： The present invention provides a removable blind fastener (2) having a first tubular element (4) comprising an arm portion (22), a second tubular element (6) comprising an arm portion (28), and an elongate screw member (8). The elements (4 and 6) are arranged in telescoping relationship one with the other and which fastener (2), when in use as a temporary fastener, is caused to secure the component parts (10 and 12) of an airframe by causing telescoping movement of the elements (4 and 6) towards each other when the screw member (8) is turned in one direction and is caused to release the component parts (10 and 12) of the airframe by causing telescoping movement of the elements (4 and 6) away from each other when the screw member (8) is turned in an opposite direction. The arm portions (22, 28) of the elements (4 and 6) are located in mutual juxtaposition for telescoping movement upon rotation of the screw member (8) as aforesaid with end portions (30a and 32a) of elongate arms (30 and 32) of the arm portions (22 and 28) being brought into engagement with a tapered portion (44) of the screw (8) whereby the arms (30 and 32) are caused to splay outwardly to bring the end portions (30a and 32a) into engagement with an underside (126) of the component (12) and moving the component (12) into secure temporary relationship with the component (10) of the airframe.
