Why Choose Semi Tubular Rivet?

Why Choose Semi Tubular Rivet?
Update Time:2017-06-14
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.

The Advantage Of Semi Tubular Rivets

1.High speed assembly. Rivets feed automatically in impact Rivet machines that cycle in approximately 3/10th of a second. Spin/orbital methods of clinching cycle in approximately 5-8 seconds
2.Can be clinched in impact rivet machines or in spin/orbital/radial style rivet machines. Air, hydraulic or mechanical presses and hand clinch tools can also be used
3.Clinch force required to fasten is typically less than 40% of solid rivets so a less expensive assembly machine is required
4.Permanent fastener with good joint strength
5.Ease of joint inspection
6.Rivet clinches can be roll-clinched, segmented (star set), spun, flared or press clinched
7.Can be used to fasten similar or different materials of multiple work-pieces. Can be applied to tightly fasten joints together or used in hinged assemblies
8.Tubular-hole rivets often used to pierce and clinch materials (leather-corrugated-plastic-rubber-fabric) without a pre-drilled or punched work-piece hole
9.Rivets can also be used with a rivet cap to improve appearance of clinched end
10.Long length rivets can be applied without buckling or bending the rivet shank
11.Inexpensive alternative to threaded fasteners
12.Virtually no scrap is produced during the manufacturing process
13.Easily adapted for automation
