Flange Bolts

A flange bolt is a type of bolt with a circular or hexagonal head and an integrated flange washer. The flange design provides a larger contact surface, increasing the bolt's load-bearing capacity while reducing stress on the connected surface. Flange bolts are commonly used in applications that require even load distribution or are subject to vibration, such as in automotive, machinery, and construction industries. They are typically made from carbon steel, stainless steel, and other materials, with various surface treatments available to ensure excellent corrosion resistance.
