Serrations bite into material for mild vibration resistance while the flange eliminates the need for a separate washer. These nuts are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. You can reuse them over and over without sacrificing strength, however, the serrations may mar the surface of your material. Also known as collar nuts.
Low–Strength Steel—About half the strength of medium-strength steel nuts, these are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.
Zinc–Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
