In the first of two articles, we explore why metalformers may benefit from performing fastening operations within the press, and how the technology successfully can be implemented. Part Two will cover troubleshooting. Self-clinching fasteners were developed more than 75 years ago as a method for attaching components to thin sheetmetal and to provide robust connections capable of withstanding axial and torque loads. They are particularly useful where components must be accessed and/or replaced, and where loose fasteners would be inaccessible or where they could pose a risk. Self-clinching fasteners create permanent, reusable load-bearing threads and, once installed, will not loosen or fall out.
