2H heavy hex nut is a nut product that is resistant to high temperature, low temperature, high pressure, high strength, and corrosion. It is suitable for high and medium pressure valves, marine, marine, chemical, fluid engineering, pressure vessels, petrochemical equipment, and other high-temperature and high-pressure situations. Used together with ASTMA193/A193B7 grade hexagonal bolts, it can prevent nut loosening and ensure equipment stability and safety. This product also has excellent resistance to hydrogen sulfide corrosion and can be used in extremely harsh working environments. 2H heavy-duty hexagonal nuts can maintain their stable performance in various high-temperature and high-pressure situations, providing users with safe and reliable solutions. For users in the fields of pressure vessels, petroleum and petrochemical, pump valves, heat exchangers, etc., we strongly recommend the use of 2H heavy-duty hexagonal nuts to meet the equipment requirements of users in high-temperature and high-pressure environments, ensuring the stability and operational safety of the equipment. By using 2H heavy-duty hex nuts, you can use and maintain the equipment with peace of mind,2H High Strength Heavy Hex Nut,GR.2H High Strength Heavy Hex Nut,ASTM A194 GR.2H High Strength Nut
