DIN 6921 Hexagon Flange Bolts have hexagon head with incomplete metric threads. DIN 6921 Hexagon Flange Bolts have a flat flange or any type of flange with locking teeth. DIN 6921 Hexagon Bolts are used together with nuts and washers to connect and fasten parts and structures. In heavy engineering, high-strength bolts are used to join steel structures. The bolt with flange DIN 6921 has high strength and provides reliable fixing even under conditions of high dynamic loads. To tighten the high-strength bolt requires great effort, so the bolt is equipped with a flange, which does not allow the material of the work piece to deform.
