Forged from high-tensile carbon steel and finished with a robust hot-dip galvanized coating, these bolts offer exceptional resistance to corrosion, shear forces, and vibrational loosening. The round head provides a smooth finish for safety, while the square neck locks into wood or metal surfaces to prevent spinning during nut tightening. Full threading allows for adjustable grip length, making these bolts versatile for various thicknesses of materials. Manufactured in our Hebei facility under strict quality control, these bolts meet international standards for structural and utility applications, ensuring long-term reliability.
