Abstract
The present invention provides a removable blind fastener 2 having a first tubular element 4 comprising an arm portion 24, 26, 28, a second tubular element 6 comprising an arm portion 30, 31, 32, and an elongate screw member 8. The elements are arranged in telescoping relationship one with the other and which fastener, when in use as a temporary fastener, is caused to secure the component parts of an airframe by causing telescoping movement of the elements towards each other when the screw member is turned in one direction and is caused to release the component parts of the airframe by causing telescoping movement of the elements away from each other when the screw member is turned in an opposite direction. The arm portions of the elements are located in mutual juxtaposition for telescoping movement upon rotation of the screw member as aforesaid with end portions of elongate arms of the arm portions being brought into engagement with tapered sills 34, 36 of the first tubular element whereby the arms are caused to splay outwardly to bring the end portions into engagement with an underside of the component and moving the component into secure temporary relationship with the component…
