Abstract
A blind fastener which can be installed by access to one side only of a workpiece comprises a pin, a sleeve, and an abutment member. The pin extends inside the sleeve and engages the sleeve at one end. The other end of the sleeve has a radially enlarged head. The sleeve is of one piece and has a radially expandable portion. The abutment member is adjacent to the sleeve head and abuts a frangible element of the sleeve head. The sleeve is inserted into an aperture in a workpiece with the expandable portion protruding beyond the blind face of the workpiece and the head abutting the near face of the workpiece. A pulling force is applied to the part of the pin extending beyond the abutment member and the expandable part of the sleeve expands radially to form a blind head against the blind face of the workpiece.
