Galvanized hex bolts are coated with zinc through two primary methods:
The bolt is immersed in molten zinc (≈450°C), forming a thick, robust zinc-iron alloy layer. Provides superior corrosion resistance (up to 50+ years in mild environments). Ideal for outdoor or marine applications. Thicker coating (50–150 μm) but may have a slightly rough surface.
Zinc is deposited via electrolysis, creating a thin, smooth coating (5–25 μm). Offers moderate corrosion protection, suitable for indoor or dry environments. Maintains precise thread dimensions due to thinner coating.
Galvanized hex bolts are essential in industries exposed to moisture, chemicals, or weather:
