Nuts are a common type of fastener, classified as a mechanical fastening component, widely used in mechanical manufacturing and other fields. Nuts are formed by a hollow cylinder and an internal threaded portion that corresponds to the screw thread. They are connected to another corresponding part by rotating the screw, thereby achieving a fixed effect. Therefore, nuts are part of the fastener family, serving functions of fixation, connection, and support. They are extensively used in various industries such as automotive, rail, aviation, marine, electronics, electrical appliances, construction, and furniture.
