BigStrip® Nuts/Collars are perfect for those occasions when it is inconvenient to use individual bigHead® Collars. They are jig-built to very high tolerances and consist of any number of nuts or collars to be welded to a 16 mm wide metal strip. Thus, they enable rows of fasteners to be mounted or positioned with extreme accuracy and speed. They are made in one-meter lengths but can be cropped or welded together for longer needs. Since these fasteners are made to order, the parts pictured are intended as reference only.
