The LEGION TOOLS® Hex Flange Serrated Nuts have a wide flange that acts as a fixed, integrated washer, which helps distribute the pressure of the nut over the part being secured. The serrated surface on the underside of the flange provides a locking mechanism by angling into the substrate to keep the nut from rotating in the loosening direction. Flange nuts also save time and money by removing the need for a washer to be added to each fastener assembly during installation.
· Zinc Plated
· IMPORTANT INFORMATION, to avoid "Pick-up" or "Galling" apply a molybdenum Di-Sulphide grease to the threads of the male fastener
