Self-piercing rivets (SPR) join two or more pieces of material using a rivet without a pre-drilled hole. Self-piercing rivets are a semi-tubular rivet driven at high force through the material layers to be joined, into a die which causes the tail of the rivet to flare out and form a joint. The process requires no hole preparation and delivers high static strength similar to, or better than, spot welding. This process produces a fatigue resistant joint that is stronger than spot welding and less susceptible to corrosion. The use of coated, lightweight and high-strength materials, such as galvanized or pre-painted steel and aluminum makes welding these materials difficult and often not possible.For general purpose use. Refer to application specifications when choosing the proper SPR.
