a depreciated fastening system, rivets are a metal fastener, with a large head on one end and a long shank. the members/plate to be connected are pre-drilled with holes, and aligned. the rivet is passed through the hole, and the end without the head is hammered to form a second head.

This system has been depreciated, because it is very labor intensive, the hot rivets are difficult to transport to high locations, and the members must be pre-drilled, which leaves less room for variance.
