A bolt is a mechanical fastener with threaded shafts. The bolts are closely related to screws, which are also mechanical fasteners with threaded shafts.
This type of fastener is usually inserted through two parts, which have aligned holes. By some definitions, whether a thing is a bolt or a screw depends on how it is used.
The bolt is inserted through the parts that all have unshielded holes, & a nut is then screwed onto the bolt to provide a clamping force & prevent axial motion.
