A blind pin fixing is provided comprising a headed pin having a series of radial grooves in that part of its stem beneath the head and a flanged body with a first circular flange and a deformable body portion projecting therefrom and arranged for the reception of the head of said headed pin so that in operation the deformable body portion is inserted through a hole in a workpiece and the fastener set by drawing the pin from the side of the flange remote from the deformable body portion so that the deformable body portion is collapsed round the hole and the collar and metal flow into the grooves locks the pin to the flanged body, the deformable body portion being of square section and formed with axial slots extending fully to the end remote from the flange so that it is divided into a plurality of, preferably four, legs which facilitate collapsing when the fastener is set. Preferably, a second circular flange is provided, spaced from the deformable body portion, that space between the two flanges providing accommodation for a component to be secured by the blind pin fixing.
