Nuts are fastening parts that are used in conjunction with bolts. They are usually in the shape of a hexahedron or other shapes, with an internal threaded hole in the center that meshes with the external threads of the bolt to achieve fastening. There is a wide variety of nut specifications, which are distinguished according to parameters such as the diameter and pitch of the thread. Types include common nuts and lock nuts. The manufacturing materials include carbon steel, stainless steel, alloy steel, etc., in order to adapt to different application scenarios. They are widely used in fields such as industrial manufacturing, construction engineering, and daily life, playing a crucial role in ensuring the stability and reliability of connections.
