Abstract
A fastener includes a pin and a collar for engaging the pin. The pin includes a pin head for engaging one exposed surface of the workpieces and a pin shank for positioning through a bore in the workpieces. The pin shank includes a second working second working edge, a second locking groove, a first working edge, a first locking groove, a breakneck groove and a pin tail having a plurality of pulling grooves. The collar includes an enlarged head and a through bore. The collar is placed over the pin shank and an installation tool is used to grip the pulling grooves. The installation tool forces the presses the collar onto the pin. As this happens, the first working edge engages the through bore of the collar and moves material from the through bore into the first locking groove to create a lock between the collar and the pin. Continued movement of the collar with respect to the pin engages the second working edge with the through bore of the collar and moves material from the through bore into the second locking groove to create an additional lock between the collar and the pin.
