Rivets

A rivet is a fastener that has a head and a shank and is made of a deformable material. It is used to join several parts by placing the shank into holes through the several parts and creating another head by upsetting or deforming the projecting shank.

 

Advantages of Rivets:

• Low cost
•  Can be used to fasten automatic or repetitive assembly
•  Permanent joints
•  Usable for joints of unlike materials such as metals and plastics
•  Wide range of rivet shapes and materials

•  Large selection of riveting methods, tools, and machines 

Riveted joints, however, are not as strong under tension loading as are bolted
joints and the joints may loosen under the action of vibratory tensile or shear forces acting on the members of the joint. Unlike with welded joints, special sealing methods must be used when riveted joints are to resist the leakage of gas or fluids.
