M20, a common bolt size in civil engineering, refers to a metric bolt with a nominal diameter of 20 millimeters. The 'M' prefix denotes that it follows the metric system, where the diameter is measured in millimeters. The size specification does not only include the diameter but also implies the thread pitch, which for M20 bolts is typically 2.5mm.

Another important aspect of bolt structure is the threading. The threading of a bolt refers to the grooves that wrap around the shank of the bolt. The threads on a bolt are what allow it to be screwed into a nut or a threaded hole in a material. The pitch, or distance between each thread, can vary depending on the application of the bolt. Coarse threads are better suited for applications where quick assembly is required, while fine threads are used for applications that require higher strength and precision
