The MBA thread Size Chart covers two pages of thread sizes in strict order of size starting at 1mm (M1) and covering the main range of metric, UNC, UNF, BA, and BSW threads up to 48mm (M48). Thread pitches are also listed, enabling a quick comparison between metric and imperial sizes, allowing for a handy guide to finding alternatives for hard-to-get threads.
