The 24-piece configuration covers metric sizes 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19mm alongside SAE sizes 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", and 15/16". This dual-standard coverage helps bridge compatibility gaps between common metric and SAE fastener systems without requiring many separate tools.
