There are a couple of different labeling systems throughout the world, so keep in Webthreads, and the smaller lead angle allows for finer tension adjustment. True Position Learn more Screws come in a wide variety of shapes and sizes, so thread callouts are used to help identify them. The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie.
