Steve, These are wire-wrap pins for mounting resistors, capacitors, diodes and the like; see Vector Electronics catalog page at: http://www.vectorelect.com/img/Web-Pdf/Access-Terminals-Pins.PDF There are also the T68 pins for components with larger leads. I insert the pins using Vector's insertion tool, then "seat" the pins all the way into the board by pressing down with a medium-hot soldering iron. Then I solder the component leads to the pins. Makes for a nice, solid breadboard and is pretty quick.
