stolle fasteners feature internal threaded holes and are generally shaped as flat hexagonal prisms, though flat square prisms or flat cylindrical shapes are also available. They are used in conjunction with bolts, studs, or machine screws to securely connect two components into a single assembly. Nuts operate by using the friction between the nut and bolt for self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are implemented to ensure reliable nut locking. As an essential component for all manufacturing machinery, they are categorized by material into
