An ASME B18.2.1 hex cap screw adheres to slightly tighter tolerances compared to a hex bolt, particularly concerning the head height and shank length. This distinction in tolerances ensures that an ASME B18.2.1 hex cap screw will consistently fit into spaces where a hex bolt is installed. However, there might be instances where a hex bolt, due to its potentially larger size, might not be suitable for applications specifically designed for a hex cap screw.
