Rivet Types

The standard structural or machine rivet has a cylindrical shank and is either hot- or cold-driven.
Following are types of rivets.

Various Types of Rivets

(a) Counter Sunk Head.

(b) Counter sunk Head with chamfered top.

(c) Counter sunk Head with round top.

(d) Globe head.

• Boiler Rivet:It is simply a large rivet with cone head.
• Cooper's Rivet:  A cooper's rivet, used for barrel-hoop joints, is a solid rivet with a head like that is in figure below which has a shank end that is chamfered.

 

• Shoulder Rivet: A shoulder rivet has a shoulder under the head.
• A tank rivet, used for sheet-metal work, is a solid rivet with a button, countersunk, flat, or truss head.
• A tinner's rivet, used for sheet-metal work, is a small solid rivet with a large flat head.
• A compression or cutlery rivet consists of a tubular rivet and a solid rivet. The hole and shank are sized to produce a drive fit when the joint is assembled.
• A blind rivet is intended for use where only one side of the joint is within reach. The blind side is the side that is not accessible.

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.
