- Standard thickened raw material for high load capacity & fracture resistance: Precisely forged premium carbon steel with uniform thick shank and regular threads, featuring high tensile strength and excellent ductility against bending and breakage.
- Galvanized anti-corrosion coating for long service life: Hot-dip galvanized or blue-white zinc finished with uniform adherent coating free of missing plating and peeling for rust & aging resistance.
- Complete accessory set for hassle-free installation: Pre-assembled full set including bolt, expansion sleeve, nut, flat washer and spring washer with no extra parts required.
- Standardized production for project acceptance compliance: Mold-based standardized manufacturing ensures consistent batch quality and minimal dimensional tolerance, achieving high installation yield and low wastage to meet conventional project inspection standards.
