Hex nut sizes are specified based on the diameter and thread pitch of the corresponding bolts and screws. A hex nut size chart provides a comprehensive reference for identifying the appropriate nut size for specific bolt and screw dimensions. The chart typically includes the nominal diameter, thread pitch, and across-flats dimensions for each nut size, allowing for easy selection and compatibility with corresponding fasteners. Hex nut size charts are essential tools for engineers, construction professionals, and maintenance personnel to ensure the proper selection and use of hex nuts in various applications.
