Question: what does m24 x 2 mean?
Answer: M means metric; dd is the full millimeter diameter of the threaded shank; and pp is the pitch in millimeters; and LL is the length in mm. If seems your fastener is describing the thread of a threaded rod or a nut, as 24 mm with a 2 mm pitch. ... A 2 mm length on a 24 mm dia bolt would be ridiculous.
