Many performance and quality indicators of hexagonal nuts are provided by the base material. Even for goods with large quantities as generally required, such as fasteners, the application of technology like high-speed cold heading and fully automatic continuous heat treatment production lines also demands higher standards for the hardness of the cold heading rod material, the quality fraction of chemical composition, and the uniformity of the raw material's rod properties.

Hexagonal nuts are used in a wide variety of applications and environments. As connecting components for the main unit and parts, they bear the basic performance requirements of the main unit and the basic functions of the components, and must adapt to various conditions such as high temperature, high pressure, low temperature, vibration, corrosion, heavy loads, alternating stresses, resistance to shearing and twisting.
