Use self-piercing rivets to join similar or dissimilar materials, such as steel, stainless steel, aluminum, brass and certain plastics and fibers. Self-piercing rivets often provide the best fastening solution when spot welding is difficult or impossible, such as with zinc-coated steel (automotive, HVAC and building applications), pre-painted metal (white goods) and aluminum (signs).

A self-piercing rivet joins two or more layers of material. The rivet first pierces the top layer of material. The anvil then upsets the rivet and causes it to flare within the bottom layer, thus forming a mechanical interlock.

Self-Piercing Rivet Advantages:

Eliminate the need to pre-punch, drill or align holes

Reduce assembly time and component cost

Pierce and fasten in one step

Easy to automate for high speed operation

Join dissimilar materials

Cleanly join coated/painted material

Ensures permanent assembly

Excellent mechanical strength and fatigue performance; highly repeatable results

Enhanced, uniform appearance (flush-finished/countersunk heads available)

Self-sealing joints that can be air- and water-tight
