Flange bolts are an integral bolt composed of two parts: hexagon head, flange (the gasket under the hexagon is integrated with the hexagon) and the screw (cylinder with external thread). It needs to be matched with the nut for tightening. The part that connects two through holes, so the bolt connection is a detachable connection.
Flange bolts are composed of hexagon heads and flange plates. The "ratio of supporting area to stress area" is larger than ordinary bolts. Therefore, this type of bolt can withstand higher pre-tightening force and has better anti-loosening performance, so it is widely used. Used in automobile engines, heavy machinery and other products.
