Self-Piercing Rivets & High-Strength SPR Fasteners
Self-piercing rivets are generally semi-tubular rivets used to clinch sheets of material together to produce a strong, fastened joint. Self-piercing rivets are valued for their efficiency, providing a clean finish with no pre-punched holes or drilling required, often increasing mass production speed.

What Are the Benefits of Self-Piercing Rivets?
Self-piercing rivets provide strong, permanent fastened joints that require little prep work and are easy to visually inspect. They can be used on surface materials that cannot be welded or dissimilar material combinations. These fasteners are an ideal solution for high-speed assembly and are adaptable to automation. There is no need for pre-drilled or punched workpiece holes and self-piercing rivets won’t destroy painted or coated finishes.
How Do You Use Self-Piercing Rivets?
Self-piercing rivets often replace spot welding and other “button” style clinch methods when a stronger fastened joint is required. The rivet is driven through the top sheet of work-piece material and the bottom sheet is then stretched or extruded into a forming die (anvil). As the bottom sheet is extruded into the anvil form, the tubular end of the rivet is flared out on the forming die, securing the sheets together. Depending on rivet length and anvil selected, the flared end of the rivet can be designed to pierce completely through the sheet layers or can be flared within the bottom sheet. When piercing leather or other soft materials, a work piece material “slug” is created when the tubular hole at the end of the rivet is driven through the workpiece and remains up inside the tubular end of the rivet.
