The difference between bolt and screw

Screws are just common parlance of fasteners. They include: bolts, screws, nuts, as long as there are threaded fasteners, screws, nuts, bolts and screws all have one thing in common: they all have threads. Tips for distinguishing bolts from screws: 1. Bolts: mechanical parts, cylindrical, threaded fasteners with nuts.A type of fastener consisting of a head and a cylinder with an external screw, which is fitted to a nut and used to fasten two parts connected with a through hole.This connection is called bolt connection.If the nut is removed from the bolt, the two parts can be separated, so the bolt connection is a removable connection. 2. Screw: it is also a type of fastener composed of the head and screw, which can be divided into three types according to the usage: machine screw, set screw and special purpose screw.The machine screw is mainly used for the fastening of the part with a fixed thread hole, and the fastening connection between the part with a through hole, without the need of nut fitting (this kind of connection is called screw connection, which is also a detachable connection;It can also be fitted with a nut for a fastening connection between two parts with a through hole.The setting screw is mainly used to fix the relative position between two parts.Special purpose screws such as ring screws for lifting parts. Classification purposes 1. Bm =1d double-end stud is generally used for connection between two steel fasteners;Bm =1.25d and bm=1.5d are generally used for connection between cast iron and steel.Bm =2d twin-end stud is generally used for connecting aluminum alloy and steel.The preceding connector is provided with an inner threaded hole, while the latter one is provided with a through hole. 2. The threads at both ends of the equal length double-end stud shall be matched with the nuts and washers for two connecting parts with through-holes. One end of the welding stud is welded on the surface of the connecting piece, and the other end (threaded end) passes through the connecting piece with the through hole, and then the washer is put on, and the nut is turned on, so that the two connecting parts become one whole.
