end 27 of the fastener will seat and position the upper annular surface 18 of the fastener 10 in line with the upper edge 22 of the plate member 21 the width of the hole 25 is substantially equal to the external diameter of the sleeve 14 with sufficient clearance to accept the sleeve 14 a laterally extending notch 30 is cut into each side of slot 25 and into plate member 21 approximately one half of the way down hole or slot 25 the location of such notch is dependent on where one wishes to upset the fastener 10 as to be described fastener 10 is positioned over and in alignment with the hole 25 in plate member 21 as the fastener 10 is lowered into hole 25 the sides of slot 17 in head 12 slidingly engage the side surfaces of plate member 21 while the sleeve portion 14 of fastener 10 is located in the fastener hole 25 the fastener 10 is firmly secured within the hole 25 of plate 21 by screwing the tip of a high strength threaded draw rod into the threaded bore portion 16 of sleeve 14 and while bearing against the upper annular surface 18 of fastener 10 as by an anvil to keep the fastener in position an upward tension is applied to the draw rod to upset the thin walled portion of sleeve 14 the unthreaded portion in sleeve 14 adjacent to the head 12 and adjacent to the thick walled threaded bore portion 16 which action effects a bulging or outward folding in such location as at 32 depicted in fig4 the bulged or buckled portion 32 enters into notches 30 since the notches offer no resistance to the formation of the bulge.
