Steel:  (Also called Mild Steel and Low Carbon Steel)  This is the most common material for use in fasteners.  Steel is an alloy consisting of mostly iron, and a small percentage of carbon, (between 0.05 – 1.1%) It is the least expensive metal.  It is strong, has good workability, and can be produced in a wide variety of forms.  Its chief disadvantage is its susceptibility to corrosion (rust) in an un-plated, unprotected form.  Its other drawback, in aerospace applications, is that steel is about three times heavier than aluminum, while not offering any great advantage in strength.  Steel is magnetic.  Most mild steel used for rivets is heat treated, although there are some exceptions.  Most steel rivets will have some form of protective finish or coating when delivered from the mill (factory) to prevent corrosion.  Most steel for commercial applications will be plated zinc with a clear chromate.  Most steel for military or aerospace applications will be plated cadmium with a yellow chromate.  

Drive: A drive rivet is a form of blind rivet. The body of the drive rivet is hollowed-out out and a pin sits in the hollowed-out portion. This pin protrudes past the head of the rivet, and is designed so it can be driven into the body of the rivet, with an ordinary hammer. The end of the shank is divided into quarters, or thirds, to allow it to be deformed. As the pin is hammered into place, it forces the ends of the rivet to splay outwards, pulling and clinching the material into place.

Drive Rivet:  A drive rivet is a form of blind rivet. The main virtue of this rivet is that it can be installed without special tooling. It can also be used in blind-hole applications, in wood or low-density materials.

Flange:  Large Flange Head.  In blind rivets, this style refers to a wide diameter protruding head, which is used when a large bearing surface is required.  Somewhat the same as a brazier head style in a solid rivet.
