Brass:  Brass is a copper-based alloy, which contains zinc as its main alloying element. (65% copper, 35% zinc.)  CDA260 or CDA270 is the most common alloy of brass used in rivets. It is stronger than copper, due to the zinc content.  It is not magnetic.  Brass rivets can be used in plain, un-plated finish, or can be plated with nickel or black oxide finish.  

Rivet Nuts:  A rivet nut is a form of internally threaded insert.  It is usually a heavy-duty form of threaded insert, with a thicker head and body, and class 3 threads, than most other threaded inserts.  To install a rivet nut, a special tool with a threaded stud engages the threads of the rivet nut and pulls upward.  This causes a portion of the body of the rivet nut to deform, and expand against the reverse side of the material being fastened, forming a secure, permanent joint, that a screw or bolt can be attached to.  Rivet nuts come in a variety of materials, in countersunk and protruding head styles, open end or closed end, and with or without an indexing key, which serves to keep the rivet nut from spinning in its joint.  Common uses include leg levelers in appliances, electronic cases, and to add attachments such as luggage racks to automobiles and components in boats, motorcycles, and RV’s.

Flat:  Flat Head.  A protruding head style rivet that is level on the top, resembling the head of a nail.  AN441 and AN442 series. (and others)
