Galvanized flange bolts are manufactured from high-quality carbon steel (Grade 4.8/8.8/10.9/12.9/14.9) and comply with GB/T16674/DIN6921/GB5787/GB5789 standards. With an integrated flange washer under the head, they eliminate the need for additional washers, increasing the bearing surface area, evenly distributing clamping force, and effectively preventing loosening. The galvanized surface treatment provides excellent corrosion resistance and rust protection, making them widely used in automobiles, construction machinery, electrical equipment, and steel structures. Customization is available for full specifications, including thread length, thread type, and surface treatment as per customer requirements.
