Bolt - a fastener in the form of a rod with an external thread, as a rule, with a hexagonal head for a wrench, forming a connection using a nut or other threaded hole. Before the appearance of threaded connections, various various products of elongated cylindrical shape were called bolts, such as, for example, a crossbow bolt, but the widespread use of screw bolts practically replaced other meanings of the word from the language.
