Low-Strength Steel Thin Hex Nuts
Also known as jam nuts, these 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. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels.
