Which Is Nut and Which Is Bolt Understanding the Difference

The spiral grooves carved around the center of a nut, technically referred to as threads, allow it to be securely gripped while still enabling easy removal. This design is essential for its functionality.
Bolts, on the other hand, are metal components with a cylindrical stem and threaded ends, featuring a head on one side for secure handling. They play a crucial role in threaded connections. While some bolts are fully threaded, others only have threads at the ends. Bolts come in various lengths and diameters, whereas nuts are typically standardized to a single size. The choice of bolt depends on the thickness of the material between the bolt's head and the nut. Both nuts and bolts can be manufactured from any type of metal.
Understanding which is nut and which is bolt is essential for selecting the right components for specific applications.
