A flange bolt is an integrated bolt consisting of a hexagonal head, a flange plate (with a gasket and hexagonal fixing integrated below the hexagon), and a screw (a cylindrical body with external threads).
8.8-10.9-12.9 grade, high-strength color zinc plated flange bolt, stainless steel hexagonal screw, high-strength anti slip flower toothed belt pad, full tooth semi threaded bolt
The flange bolt is composed of a hexagonal head and a flange plate, and its “support area to stress area ratio” is larger than that of ordinary bolts. Therefore, this type of bolt can withstand higher pre tightening forces and has better anti loosening performance. Therefore, it is widely used in products such as automotive engines and heavy machinery.
