• Flange bolts are fully-threaded fasteners with a hexagonal head for use with a wrench or a socket drive. Sometimes called Frame bolts, flange bolts are different from standard bolts as they are designed with a circular flange or a skirt under the head that functions as a built-in washer and distributes the force evenly across the surface to which it will be fastened. The flange helps compensate for excess space in large or misaligned holes yielding increased resistance to rotational loosening.
• Made of Class 10.9 tempered medium carbon steel similar to US Grade 8 and possess strong wear resistance as well as high tensile strength. Mostly used for automotive and fastening applications such as steering and suspension parts, cylinder, and flywheels, and also for high strength mechanical applications and forged parts. The Yellow Zinc finish, aside from the golden aesthetic, provides a marginally better protection from rust and corrosion against water contact than clear zinc or black oxide.
• M8 - M12 Diameter JIS (Japanese Industrial Standard) Flange bolts have smaller head sizes than ISO and ANSI type bolts and are commonly used for truck, car, ATV, snowmobile, and motorcycle frames, exhaust, and for securing the outer casing protecting the engine and transmission. This type of bolt is suitable for any use that requires mounting surface protection.
• It is important to make sure that when buying a nut to go along with this flange bolt, the steel class (hardness) of the nut is the same as that of the bolt for an optimal strength combination.
