Bolts are threaded metal fasteners with an external (male) thread, designed to pass through aligned holes in parts and be secured by a matching nut, creating a strong, often removable joint, unlike screws that typically form their own threads or mate with pre-tapped holes and are tightened by turning their head. They consist of a head and a threaded cylindrical body, commonly made from steel, used across construction, machinery, and automotive industries to join components.
