M5 Flange Serrated Hex Full Nuts A2 Stainless Steel (304)

A2 (stainless steel) flange nuts are used in industries like automotive, machinery, and construction for secure, high-strength fastening, especially on uneven surfaces or where vibration is a concern. Their integrated flange acts as a built-in washer, distributing the load and preventing damage to the material. Serrated versions provide added vibration resistance, making them ideal for applications like exhaust systems or other areas prone to loosening from movement.
