Mil. Spec. 18-8 Stainless Steel Thin Hex Nuts

Choose these nuts for their adherence to strict military standards for material and construction. Made of 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. Also known as jam nuts, they are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place.
