A screw and a bolt are similar types of fastener typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). The "M" designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres (e.g. an M6 screw has a nominal outer diameter of 6 millimetres).
