The factory head is a pre-formed head on one end of a rivet. When finished, the tail will resemble a dumbbell, completing the riveted joint.
The rivet is deformed by pounding or smashing the tail, which flattens the material and causes the tail to expand by about one and a half times the original diameter of the stem. Rivets are a well-known and widely used mechanical fastener.

They are made up of a prefabricated head and shank that are inserted into the material to be joined, as well as a second head that allows the rivet to act as a fastener at the free end through various means known as a setting. To distinguish between the two ends of the rivets, the original heads are referred to as factories heads, while the deformed end is referred to as a shop head or buck-tail. It is a metal headed pin or bolt used to join two or more pieces by passing the shank through a hole in each piece and then beating or pressing down the plain end to form a second head To put it another way, pounding or pulling creates a new “head” by breaking off the “tail” material flatter on the other end, resulting in a rivet the size of a dumbbell. When installing, the rivet is inserted into a punched or drilled hole, and the tail is screwed or buckled so that it protrudes approximately 1.5 times the original shaft diameter, securing the rivet. The tail is the opposite end of the head. Rivets are made up of a smooth cylindrical shaft with a head at one end before they are installed. Rivets are non-threaded fasteners that are most commonly made of steel or aluminum.
