The purpose of this hole is to reduce the amount of force needed for application by rolling the tubular portion outward. The force needed to apply a semi-tubular rivet is about 1/4 of the amount needed to apply a solid rivet. Tubular Rivets can also be used as pivot points (a joint where movement is preferred) since the swelling of the rivet is only at the tail. Permanent fastener with good joint strength. Rivet clinches can be roll-clinched, segmented (star set), spun, flared or press clinched. Tubular-hole rivets often used as and clinch materials (leather-corrugated-plastic-rubber-fabric) without a pre-drilled or punched work-piece hole. 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 Rivets can also be used with a rivet cap to improve appearance of clinched end. Long length rivets can be applied without buckling or bending the rivet shank. Inexpensive alternative to threaded fasteners. Easily adapted for automation.
