The rivet jaws control the rivet prior to and as the rivet is being delivered to the anvil during assembly. The jaws are attached by jaw legs and often have booster springs attached to the jaw legs to insure the jaws maintain the required amount of squeeze force on the rivet to insure proper feeding. When the rivet machine is cycled, the jaws move downward toward the anvil and stop just above the anvil pin (spring loaded anvil pin) or just above the work piece (on some countersunk hole applications). As the driver (or ram) pushes the rivet head down through the jaws, the rivet is then delivered through the work piece to the anvil form where the actual clinching takes place.

A semi-tubular rivet has a manufactured head on one end and tubular shank hole-depth of less than 112% of the shank diameter of the rivet. A tubular rivet has shank hole-depth equal to or greater than 112% of the shank diameter. Common rivet head styles are oval, truss, button, flat and countersunk. Among the raw materials used are steel, stainless steel, aluminum, brass, and copper. Rivet plating and coating options are selected by end user dependent on the application.Semi-tubular and tubular rivets are excellent fasteners to quickly and inexpensively join work-piece materials together. The tubular portion of the rivet may be fastened to a tight or loose (hinged assemblies) fit depending on the application. Riveted work-pieces are most often joined together by impacting or compressing the tubular end of the rivet with a crimping die (rivet anvil). The length of the rivet shank must be long enough to pass through work-piece with enough shank length left over for clinching process. The tightness of the clinched joint is determined by the amount of force applied to the clinched end of the rivet and can easily be adjusted.
