Bolts are threaded rods or pins that fasten objects together. They usually have a head at one end and a thread at the other.
Bolts are secured by threaded nuts of the same configuration. For example, a metric bolt would require a metric nut to secure it. Similarly, an English bolt would require an English nut.
Bolts serve many purposes in construction and fabrication, and there are many specially designed bolts used for specific types of manufacturing.
