A194 2H Heavy Hex Nuts Carbon Steel Zinc Plated

ASTM A194 Grade 2H Quenched and tempered carbon steel zinc plated heavy hex nuts

The ASTM A194 specification covers a variety of carbon, alloy, and stainless steel nuts. Ranging in sizes ¼ through 4 inches, 2H nuts are intended for high-pressure or high-temperature applications in a plain (uncoated) finish. To identify A194 nuts, note the 2H on the nut’s face. A194 2H nuts can be coated. Zinc coated nuts will have a ZN marked after the grade (example: 2HZN). A194 2H nuts are often paired with A193 B7 steel or F1554-105 steel, typically as all thread studs, hex bolts, or double end rods. Often, you will find these nuts in high strength applications in fields including oil and gas.
