Looking for a fastening solution that creates permanent, reliable connections in sheet metal? These self-clinching nuts from Penn Engineering's CLS series are exactly what you need. Whether you're working on custom enclosures, brackets, or any sheet metal project, these fasteners provide a clean, professional finish that won't loosen over time.
Installation is surprisingly simple. Just place the nut in a properly sized hole in your sheet metal (0.344 inches diameter) and apply parallel pressure to the head. The surrounding metal cold flows into the undercut, creating an integral part of the sheet. The serrated clinching ring prevents rotation, ensuring your fastener stays exactly where you put it. No more worrying about nuts backing out under vibration or stress.
These aren't just any fasteners—they're made from 300 series stainless steel with a passivated finish for superior corrosion resistance. The CLS/CLSS design is specifically engineered for steel or aluminum sheets with a hardness of HRB 70 or less (HB 125 or less), making them ideal for most sheet metal applications. Each package includes 10 nuts, giving you plenty for multiple projects.
Stop struggling with traditional nuts that loosen or require special tools. These self-clinching nuts create a permanent, vibration-resistant connection that looks professional and functions flawlessly. Whether you're a professional fabricator or a dedicated DIY enthusiast, these fasteners will become your go-to solution for clean, reliable sheet metal assembly.
