Not all challenging rivets have to have a complex geometry. The chosen metal and application can introduce challenges as well. Chicago Rivet produces millions of fasteners for the automotive industry that must be “defect-free” – tougher than most industry standards. In this example, a medium carbon steel conforming to F-2282 industry standard, has inherent cracking potential due to the nature of the material. However, in order to produce a defect-free product, many avenues had to be explored – from challenging the source material suppliers, modifying internal processes, and introducing highly automated optical (camera) detection systems, Chicago Rivet continues to meet its customers’ intense scrutiny.
