Choose these flange locknuts for their adherence to strict military standards for material and construction. They have an irregularly-shaped thread that grips the bolt for a stronger hold than nylon-insert flange locknuts. A flange that distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. They're not reusable. A cadmium yellow-chromate plating provides corrosion resistance in wet environments. Height includes the flange. Locknuts with lubricant keep screws from binding to the locknuts while you tighten them. They’re often used with screws made from soft metals, such as aluminum, which are more likely to bind to the locknuts than harder materials such as steel.
