Manufactured from medium carbon steel and heat-treated to meet ASTM A194 Grade 2H requirements, the nut offers excellent mechanical properties, making it suitable for high-pressure, high-temperature, and critical bolted joint applications. The hot-dip galvanized (HDG) coating provides a thick protective zinc layer that significantly improves corrosion resistance and extends service life in outdoor, marine, and harsh industrial environments.
