PROBLEM TO BE SOLVED: To provide a blind fastener which can be used as an appropriate stop for arresting displacement of slidable members and which alleviates the problems of existing stops, particularly those associated with window winders. SOLUTION: The present invention is directed to the blind fastener, usually a blind rivet, comprising a mandrel and an elongate cylindrical body mounted on a stem of the mandrel so as to extend co-axially about a central axis A of a blind rivet, the body having a flange at one end and a tail end at an axially opposed end, for insertion through a hole in a workpiece, the mandrel being directed to the blind rivet having a mandrel head in operative engagement with this tail end for transmitting force thereto during setting of such fastener, wherein the body has two different external diameters d, D and a radially extending shoulder therebetween such that the external diameter D of the body adjacent to the flange is greater than the external diameter d of the body adjacent to the tail end, wherein the body between this shoulder and the flange is at least partially encased in a resilient, shock absorbing material.
