ABSTRACT:
In general a torque controlled blind bolt for securing workpieces is shown and which blind bolt has a core pin with a blind side head and a plurality of threads and a nut adapted to be threaded onto the pin threads; the blind bolt which has a main sleeve structure and an expandable blind side sleeve structure is set by torque applied between the pin and nut which causes the expandable sleeve to be expanded by the pin head and to thereby form a load bearing blind head; the blind fastener includes a grip adjuster structure which defines a cavity having a depth selected to define the grip range of the fastener with the grip cavity generally located externally of the workpieces; an anti-rotation structure is formed between the pin head and the expandable sleeve structure to inhibit relative rotation in response to the torque applied between the nut and the pin.
