A flange bolt (901000285) is different from the standard bolt because of its broad surface under the head. The head includes a ridge and skirts that distribute the load and ensure greater holding power. 

This part is usually used in vehicles or anywhere where a head bolt is required. After all, they offer four times the bearing area than a standard hex screw. Some mechanics recommend replacing the standard bolt and washer with springs and flange bolts to increase strength and reliability in a car’s exhaust, for example. 
Automotive flange bolts are usually made from alloy steel making them durable enough to handle around 150,000 PSI. Other types of flange bolts include cadmium plated bolts, zinc chromate bolts, and anodized aluminum and stainless steel bolts.
