Our A563M Hex Nut is a metric heavy hex nut manufactured in accordance with ASTM A563M, specifically designed for use with high-strength structural bolts such as A325M and A490M. The A563M DH Heavy Hex Nuts (DH stands for"heavy hex"with larger dimensions) provide a thicker body and wider bearing surface compared to standard hex nuts, ensuring better load distribution and resistance against loosening under high preload. As Heavy Hexagon Structural Nuts, they are available in property classes including 8S, 8S3 (weathering steel for atmospheric corrosion resistance), and 10S, matching the strength requirements of Grade 8.8 and Grade 10.9 bolts. These nuts are widely used in steel frame connections, bridges, high-rise buildings, industrial plants, and heavy machinery.
