SUGGESTED WORK PIECE HOLES & CLINCH ALLOWANCES Over 4 Times and up to 8 Times Shank Diameter Up to and including 4 Times Shank Diameter Length Tolerances Expressed as plus/minus SEMI-TUBULAR RIVET LENGTH INCREMENTS, TOLERANCES & FILLET RADIUS STANDARD OVAL HEAD SEMI-TUBULAR RIVET DIMENSIONS Virtually no scrap is produced during the manufacturing process.Inexpensive alternative to threaded fasteners.Long length rivets can be applied without buckling or bending the rivet shank.Rivets can also be used with a rivet cap to improve appearance of clinched end.Tubular-hole rivets often used to pierce and clinch materials (leather-corrugated-plastic-rubber-fabric) without a pre-drilled or punched work-piece hole.Can be applied to tightly fasten joints together or used in hinged assemblies Can be used to fasten similar or different materials of multiple work-pieces.

Permanent fastener with good joint strength.Clinch force required to fasten is typically less than 40% of solid rivets so a less expensive assembly machine is required.Air, hydraulic or mechanical presses and hand clinch tools can also be used Can be clinched in impact rivet machines or in spin/orbital/radial style rivet machines.Spin/orbital methods of clinching cycle in approximately 5-8 seconds Rivets feed automatically in impact Rivet machines that cycle in approximately 3/10 th of a second.

Customization Options Rivet Head Styles 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 length of the rivet shank must be long enough to pass through work-piece with enough shank length left over for the clinching process. 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 development of conventional semi-tubular rivets was based on aluminium-aluminium joints as well as (high-strength) steel-aluminium joints. The tubular portion of the rivet may be fastened to a tight or loose (hinged assemblies) fit depending on the application. Semi-tubular and tubular rivets are excellent fasteners to quickly and inexpensively join work-piece materials together. Semi-Tubular & Tubular Rivet Applications A semi tubular rivet clincher has a manufactured head on one end and tubular shank hole-depth of less than 112% of the shank diameter of the rivet.Ī tubular rivet, also known as a hollow rivet, has shank hole-depth equal to or greater than 112% of the shank diameter.
