The "M" designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres. Here is the metric thread sizes table defines standard metric external thread size M1.6 to M18 per. Metric Threads come in different pitch sizes for a given diameter: coarse pitch and fine pitches. Fastener and Screw / Bolt Design, Formula and Calculations. To understand classes, you first need to understand the terms Allowance (Sometimes referred to as deviation) and Tolerances. If you don't know the pitch, choose coarse threads; they're the industry standard. Superfine pitch metric threads are occasionally used in automotive components, such as suspension struts, and are commonly used in the aviation manufacturing industry. For those with a diameter smaller than 1/4", screw size is indicated by a These thread sizes and classes represent bolts and screws, as well, as other standard external threads.

The V-shaped thread form has a 60 flank angle and male and female threads are both parallel. Japan has a JIS metric screw thread standard that largely follows the ISO, but with some differences in pitch and head sizes. In practice this means that one can measure the diameter over the threads of a bolt to find the nominal diameter Dmaj, and the inner diameter of a nut is Dmin. Small letters represent external threads, while capital letters represent internal threads. The terms coarse and fine have (in this context) no relation to the manufacturing quality of the thread. For example, a M6 x 1 mm has a 6 mm thread diameter and has 1 mm between threads. This corresponds to the second number of the thread size. Lubrication Data Apps ISO metric threads consist of symmetric V-shaped thread.
