A square nut is a type of fastener with a square shape that is designed to be used with a square or hexagonal wrench. It is used to secure threaded bolts, screws, or studs in various applications. Square nuts have four flat sides and are often used in conjunction with square bolts or machine screws.

Key features of a square nut include:

  1. Square Shape: The nut has four flat sides that form a square shape. This design allows for easy gripping and turning using a square wrench or a crescent wrench with a square opening.

  2. Threads: Square nuts have internal threads that match the external threads of the bolt or screw they are intended to fasten. The threading allows the nut to be screwed onto the bolt, creating a secure connection.

  3. Materials: Square nuts can be made from a variety of materials, including steel, stainless steel, brass, and other metals, depending on the application's requirements.

Square nuts can provide a more secure and stable connection than hex nuts in certain situations. However, their use is less common compared to hex nuts and other types of fasteners. When using square nuts, it's important to ensure that the mating bolt or screw has matching threads and dimensions to achieve a proper fit and connection.
