Flange Bolts are threaded fasteners with a hex head and an attached formed flange. The non-serrated flange acts like a washer providing a broader bearing surface; the serrated flange also acts like a washer but also provides some anti-loosening protection. Flange bolts are also referred to as frame bolts as they are commonly used in frame applications such as truck frames and bed frames.
