SelfPiercing Rivets for Aluminum Body FasteningSelfpiercing rivets ( SPR ) join two or more pieces of material using a rivet without a predrilled hole.Selfpiercing rivets are a semitubular rivet driven at high force through the material layers to be joined . into a diewhich 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 suscepti ble to corrosion.The use of coated . lightweight and highstrength materials . such as galvanized or prepainted steel and aluminumm akes welding these materials difficult and often not possible.Selfpiercing rivets use a special tool that presses the rivet into place and requires access to both sides of mating Panels Ford : W708713S900 W708713S900 FORD : W708713S900 FORD : W708713S900
