Uxcell 100 Pcs 3mm X 16mm Aluminum Flat Head Semi-Tubular Rivets Silver Tone

Descriptions: Semi-Tubular Rivets (also known as Tubular Rivets) are similar to solid rivets, except they have a partial hole (opposite the head) at the tip. 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. Rivet clinches can be roll-clinched, segmented (star set), spun, flared or press clinched. Tubular-hole rivets often used to pierce and clinch materials (leather-corrugated-plastic-rubber-fabric) without a pre-drilled or punched work-piece hole.
