Flange Bolt with Flange Nut is a nut that has a wide flange at one end that acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. Flange Bolt with Flange Nut is usually used in vehicle frames, especially in trucks and anywhere a head bolt is required. This features a nozzle, thereby speeding the assembly while eliminating the washer. This has a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight.
