RIVET
Rivet (fr: Rivet): A permanent fastening tool used in various forging processes. A rivet consists of a smooth cylindrical shaft (called – the tail) with a head on one end. On installation, the rivet is placed in a drilled or punched hole, and the tail is deformed, so that it expands to about 1.5 times the original shaft diameter, thus holding the rivet in place. Simply put, smashing the “tail” material flatter creates another head on the other end of the rivet, which results in a rivet that is roughly shaped like a dumbbell. The original head of the rivet is called – the factory head; the deformed end is called – the shop head or buck-tail. There are different types of rivets, some of them are: solid/round head rivets, blind rivets, semi-tubular rivets, drive rivets, flush rivets and other.
ROD
Rod (fr: Tige d’acier): Any rolled steel or steel with a circular cross section can be considered a bar or a rod. Generally, a rod is from 3/16 to 1/2 inch in diameter. In most cases, today’s rods are rolled in long lengths and coiled.
