Strux® Clinch Nuts provide an internal nut member in sheet metal 1.00 mm to 3.00 mm thick. These fasteners can be fed manually, or you may use any equipment normally used to feed rivets, weld nuts or conventional clinch nuts. They are available in sizes ranging from M4 to M116 (#6 to 5/8"), and can be custom engineered to meet your specific application needs.
