American A307 galvanized high-strength bolt

Bolt: Mechanical component, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a Screw (a cylindrical body with external threads) that needs to be matched with a nut to fasten and connect two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, it can separate the two parts, so bolt connection is a detachable connection. When connecting, it is necessary to unscrew the nut from the bolt to separate these two parts, and then fix them onto the connecting piece. Installing the nut onto the bolt can provide a good tightening effect.
