Galvanized DIN6921 flange bolts refer to a layer of zinc metal covered on the surface of the bolt to improve its corrosion resistance and durability. It can effectively prevent the bolt from being corroded by air, water and other chemicals, thereby extending its service life.
The head of the DIN6921 flange bolt has a large hexagonal flange head. This design can provide greater torque, making it easier to tighten the bolt and bring better sealing effect to avoid liquid or gas leakage.
The material grades of galvanized DIN6921 flange bolts include grade 8.8, grade 10.9, grade 12.9, A2-70, A4-70, A4-80, etc., ensuring the strength and quality of the bolts.
In addition to galvanizing, common surface treatments include ordinary blue and white zinc plating, ordinary color zinc, hot-dip galvanizing, environmentally friendly color zinc, environmentally friendly blue and white zinc, environmentally friendly Dacromet, etc.
Galvanized DIN6921 flange bolts are widely used in photovoltaic, machinery, transportation, automobile, chemical, heavy industry, construction and other industries
