Mil. Spec. 18-8 Stainless Steel Nylon-Insert Locknuts
Choose these locknuts for their adherence to strict military standards for material and construction. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.
