Semi Tubular & Tubular Rivets

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 the 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.
