1. A removable blind fastener comprising:
a body, a screw member, and a clamping member,
wherein the body comprises a hollow cylindrical shaft having a proximal end and a distal end and a head at the proximal end, the head being hollow with an internal end face,
wherein the shaft has an open guide channel along a portion of the shaft's length and an urge channel opposite the guide channel,
wherein the urge channel is located at the distal end of the shaft,
wherein the screw member has a threaded region that fits within the shaft of the body and wherein the screw member has a head at a proximal end that fits within the hollow head of the body, and
wherein the clamping member is arranged to fit in the guide channel and wherein the clamping member has a threaded aperture for engaging with the threaded region of the screw member, such that rotation of the screw member causes the clamping member to move along the guide channel of the body, and wherein the clamping member has an urging portion and a clamping portion, arranged such that the urging portion of the clamping member can fit within the urge channel of the body and further arranged such that when the urging portion of the clamping member is located within the urge channel of the body the clamping member is concealed within the boundary of the outer surface of the body in a retracted position and when the urging portion is not located in the urge channel of the body the clamping portion of the clamping member extends from the outer surface of the body in a clamping position;
wherein the screw member is free to move radially within the shaft and wherein the guide channel terminates before the distal end of the shaft and the threaded region of the screw member is longer than the shaft so that radial movement of the screw member within the shaft is restricted to within the internal diameter of the shaft.
