2H Heavy Hex Nut, A194 / Sa 194, Zinc Cr+3 (Inch)
2H Heavy Hex Nuts A194 / SA 194 Zinc Cr+3 are high-strength alloy steel fasteners engineered for use in high-pressure and high-temperature bolting applications. Manufactured to ASTM A194 / ASME SA 194 Grade 2H specifications, these nuts feature a heavy hex design that provides a larger bearing surface and improved wrenching strength. The Zinc Cr+3 (trivalent chrome) plating offers enhanced corrosion resistance and a bright, durable finish while being environmentally friendly compared to traditional hexavalent coatings.
Ideal for use with A193 Grade B7 bolts and other high-strength fasteners, these A194 / SA 194 Grade 2H Heavy Hex Nuts deliver reliable clamping force in critical assemblies such as flanges, valves, pressure vessels, and structural joints. The Zinc Cr+3 coating provides added protection against rust and oxidation, making them suitable for both indoor and moderately corrosive environments.
