摘要： A two piece blind fastener for securing a plurality of workpieces including a hollow sleeve having a straight shank with an enlarged sleeve head at one end and a pin having an enlarged pin head; the pin has a pin stop shoulder and a lock groove located near the pin stop shoulder; the pin head is adapted to engage the sleeve to form a bulb type blind head in response to a relative axial force applied between the pin and sleeve; the pin stop shoulder is adapted to engage a sleeve stop shoulder to direct the material of the sleeve stop shoulder substantially radially inwardly into the lock groove to lock the pin and sleeve together and to finally form a stop surface on the sleeve for stopping axial movement of the pin through the sleeve; in addition the pin has an expander portion adapted to expand the sleeve shank radially outwardly to fill the openings of the workpieces and with the expander portion having a grooved section with alternate relief grooves and expander segments with the relief grooves receiving excess material of the sleeve after hole fill and to thereby also assist in locking the pin and sleeve together.
