Hex Flange Screws are a form of hex head bolt with a wider flange under the head. The circular flange under the head serves as a washer spreading the load and providing nearly four times the bearing area of a regular hex screw. Flange bolts are commonly used in the frames of vehicles, especially trucks. Non-serrated flange bolts are most commonly used.
