A square nut is a type of fastener used in mechanical applications. It is a four-sided nut with a square-shaped cross-section, as opposed to the more common hexagonal-shaped nut. The square shape of the nut helps to prevent it from rotating, which makes it useful for applications where a regular nut might loosen over time.
Square nuts are typically used in conjunction with square bolts, which have a square-shaped shank that fits into a corresponding square hole in a component. This combination helps to prevent the bolt from rotating or loosening, even under high levels of vibration or torque.
Square nuts are commonly made from materials such as steel, brass, and stainless steel. They are used in a wide range of applications, from automotive and industrial equipment to furniture and construction projects.
