ABSTRACT:
A system for producing a first and second series of blind fasteners each in uniformly varying grip increments for securing workpieces varying in total thickness, each blind fastener comprising a tubular sleeve, a pin and lock collar, the sleeve adapted to be located in aligned openings in the workpiece with the fastener adapted to secure the plurality of workpieces together by means of a relative axial force applied between the pin and the sleeve, the sleeve having a relatively straight sleeve shank terminating at one end in an enlarged sleeve head, the first series sleeve heads being of the flush head type and the second series sleeve heads being of the protruding head type having a generally streamlined low profile configuration, each of the first series of sleeves being related to each of said second series of sleeves of the next largest grip increment such that the overall lengths of the first series of said sleeves and the related ones of the second series of sleeves are substantially the same, the pins for the first series of sleeves and the related ones of the second series of sleeves being substantially the same such that they are interchangeable, and where the fastener pin can be made by cold forming from titanium with a cold formed, tapered stop shoulder.
