2 mm thread pitch (or ‘coarse’ thread) means that these knobs have threads on the inside that measure 2 millimeters from thread peak to thread peak. This is the current version used on newer Linea Classic models. Prior to ~2013, La Marzocco previously used both this part and/or a 1 mm version. They work with any valve that uses the F_333 valve fitting. Includes bezel.
