Rivets
Rivets are specific, headed, usually non-threaded fasteners that are beaten or
pressed into place to secure two or more items together. Rivets are cylindrical
mechanical fasteners capped with a flanged or forged head on one end. Rivets
have different shaped heads, including domed, flat, or countersunk.
To secure two or more pieces of material together, a rivet is placed into a hole
cut just a bit larger in diameter than the rivet itself. During blind riveting
or pop riveting, the force transferred from the hammer actually deforms the
other end of a hollow rivet, creating a field head which secures the material
together. By hand, this is usually done by hammering the rivet into the material
with a striking plate underneath. Machine riveting can be done by heating the
rivet until it is red hot and then forging the field head onto it or by using
compression from a pneumatic or hydraulic hammer, or a smaller, hand-held rivet
tool called a rivet gun.

Rivets come in a variety of
configurations depending on the type of riveting. A tubular rivet has a
cylindrical or tapered hole at the end, which is shaped or curled back by
another tool during the setting process to form a clinch head against the
material. A rivet nut or nutsert, is a threaded rivet which is used to provide
secure, permanent hold in high-load applications.
Rivets can be made of many different materials, including steel, copper,
plastic, and other metal alloys, depending on the material being secured
together, possible weight restrictions, and the potential for corrosion. When
the weight of the materials or the possibility of corrosion is an issue, a
manufacturer may use a copper, aluminum, or plastic rivet. Plastic button rivets
may be removed and used again, and are useful in applications where materials
need to be non-conductive.
