DIN6921 Hexagon flange bolt Carbon steel M5-M20

Short Description:

The flange bolt is an integral bolt composed of two parts: a hexagon head and flange (the gasket under the hexagon and the hexagon are fixed in one) and a screw (a cylinder with external thread), which needs to be matched with the nut to fasten the parts connecting two through holes, so the bolt connection is a removable connection.
Flange bolts can withstand higher preload and have better anti-loosening performance, so they are widely used in automotive engines, heavy machinery and other products.
Our factory can customize and produce flange bolt of different specifications and materials for you, welcome your inquiry.
