Nuts are fasteners used on threaded rods. Nuts may be used alone or with other fasteners such as a washer or mating bolt to ensure the nut stays in place. A mating bolt is used to join or fasten more than one part together. In the early days, square nuts and bolt heads were the most common fasteners. This is because their shapes make them easy to manufacture. This was particularly beneficial back in those days when machines were rare. These days, square nuts and bolt heads are still used, albeit rarely, when the application requires a maximum amount of torque. A hex nut, on the other hand, are commonly used in tight spots because it has “good granularity of angles for a tool to approach from.”
