Our hex nuts comply with the ASTM A194 Grade 2H standard, it is specially designed for use in systems operating under high temperature and high pressure conditions. It is typically used with high-strength studs and bolts such as ASTM A193 Grade B7, B16. Manufactured from heat-treated medium to high carbon steel, these nuts provide long-lasting and reliable performance in heavy-duty connections. Both inch and metric threads Due to its structure, it is widely preferred in international projects.

ASTM A194 Grade 2H, made of carbon steel with increased strength high-strength nuts is a standard for. Hexagonal shape is produced. Area of use as: systems subjected to high pressure, temperature, and mechanical stress — correct.
It is preferred in systems operating under high temperature, high pressure, and heavy loads to minimize the risk of loosening and ensure long-lasting connections.
These bolts are manufactured from heat-treated carbon steel. Material selection should be based on factors such as the temperature, pressure, corrosion, and mechanical stress to which the connection will be exposed. Surface coatings should also be selected according to environmental conditions (e.g., hot-dip galvanizing – outdoor environments; PTFE – chemical resistance).
