A removable blind fastener 1 comprises a first member having an elongate body 11 with a head 12 at one end and a second member 20 having an elongate body extending from and adapted to slide relative to the first member. The second member 20 has at least one flexible finger 22A, C with a finger head at one end remote from the first member. A screw member 30 has a screw head adjacent the first member head 12 and a screw shaft 33 which passes through the first member and engages with a threaded aperture on the second member20. Rotation of the screw member 30 in one direction causes the second member 20 to slide towards the first member and biases the or each flexible finger 22A, C radially outward. Rotation of the screw member 30 in the other direction causes the second member 20 to slide away from the first member and allows the or each flexible finger 22A, C to move radially inwards. In use the fastener 1 is insertable through an aperture 40A, 50A in each of two workpieces 40, 50 which need joining together with the 12 head of the first member located against a face of one workpiece 40. Rotation of the screw member 30 causes the or each flexible finger 22A, C to expand radially outward so the finger head on the or each finger engages a face of the other workpiece 50 and causes the two workpieces 40, 50 to be drawn together as the second member 20 slides towards the first member. |
