2H Heavy Hex Nut, A194 / Sa 194, Hot-Dip Galvanization (Inch)
2H Heavy Hex Nuts A194 / SA 194 Hot-Dip Galvanized are high-strength, heat-treated steel fasteners manufactured to ASTM A194 / ASME SA 194 Grade 2H specifications. Designed for high-pressure, high-temperature, and heavy-duty applications, these heavy hex nuts feature a larger bearing surface and thicker profile for superior load distribution. The hot-dip galvanization process provides a robust zinc coating, offering excellent long-term corrosion resistance in harsh and outdoor environments.
Engineered for durability and strength, A194 / SA 194 Grade 2H Heavy Hex Nuts are ideal for use with A193 Grade B7 bolts and other high-strength fasteners in structural steel, pressure vessels, flanges, and pipeline systems. The hot-dip galvanized coating ensures superior protection against rust and chemical exposure, making these nuts a top choice for marine, construction, and industrial applications where corrosion resistance is critical.
