The idea that revolutionized production fastening When K.A. Swanstrom founded Penn Engineering & Manufacturing Corp. in 1942, he did so with a revolutionary new product: an easy-to-install, self-clinching fastener that provides load-carrying threads in metal sheets too thin to be tapped. At first, Mr. Swanstrom produced his innovative design with four machines in a Doylestown, Pennsylvania garage. This simple operation soon gave way to a modern facility in Danboro, Pennsylvania because manufacturers and engineers alike recognized the benefits of self-clinching fasteners. They not only reduced time, labor, weight and inventory on many assembly jobs, but they also opened up a whole new world for engineers and designers, making a wide assortment of thin-metal designs possible for the first time. Industry-wide acceptance led to earnest production of self-clinching fasteners shortly after World War II. As industryÕs need to hold together ultra-thin and ultra-light metals grew, so did the product line. Over the years the original self-clinching fastener design was modified to meet hundreds of new design applications. Today, PennEngineering is a global company and industry leader with manufacturing facilities in Danboro, Pennsylvania; Winston-Salem, North Carolina; Corona, California; Wilmington, North Carolina; Galway, Ireland and Kunshan China.
