Sizes that may interchange, depending on the precision needed, include 2 mm (close to 5⁄64 in (1.98 mm)), 4 mm (close to 5⁄32 in (3.97 mm)) and 8 mm (close to 5⁄16 in (7.94 mm)). In reality, a wrench with a width across the flats of exactly 15mm would fit too tightly to use on a bolt with a width across the flats of 15mm.
