GRADE 2H METRIC

GRADE 2H METRIC

Grade 2H hexagon nuts are high-strength carbon steel fasteners primarily specified under ASTM A194.

These nuts undergo a rigorous heat-treatment process of quenching and tempering to achieve the extreme durability required for high-pressure and high-temperature service. 

Key Specifications & Performance

  • Standards: Typically manufactured to ASTM A194/A194M and often follow ASME B18.2.2 dimensional standards for heavy hex nuts.
  • Common Pairing: They are most frequently paired with ASTM A193 Grade B7 bolts or studs to create secure connections in demanding industrial environments like oil and gas, power plants, and chemical processing.
  • Temperature & Pressure: These nuts are designed to maintain their integrity at temperatures up to 427 degrees C and handle intense mechanical stress.
  • Identification: Look for the permanent "2H" stamped on the face of the nut, along with the manufacturer’s unique identification symbol.
