Flange nuts have flat and serrated designs. Serrated flange nuts are fabricated with a built in serrated washer that resists loosening due to vibration.They are commonly used in assembly lines where operations are speeded by using a single fastener instead of a nut and a washer. The 304 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.
