Stainless steel hexagonal bars are mainly used for fasteners - stainless steel external hexagonal bolts, stainless steel cylindrical head internal hexagonal screws (cup heads), stainless steel internal hexagonal concave end fastening screws (concave end machine meters), stainless steel internal hexagonal flat end fastening screws (flat end machine meters), stainless steel internal hexagonal pointed end fastening screws (pointed end machine meters), stainless steel internal hexagonal column end fastening screws (column end machine meters), stainless steel countersunk head internal hexagonal screws (flat cups), stainless steel semi-circular head internal hexagonal screws (round cups).

The application prospects of stainless steel hexagonal bars are widely used in fields such as automotive parts, elevators, kitchen equipment, pressure vessels, etc., and have received unanimous praise from users. The key to application in future development is environmental protection and long lifespan. Regarding environmental protection, from the perspective of atmospheric environmental protection, the demand for heat-resistant and high-temperature corrosion-resistant stainless steel for high-temperature waste incineration devices, LNG power generation devices, and high-efficiency power generation devices using coal to suppress the occurrence of dioxins will expand. Regarding longevity, the use of stainless steel is increasing in existing bridges, highways, tunnels, and other facilities in Europe, and it is expected that this trend will spread worldwide. The lifespan of typical residential buildings in Japan is particularly short at 20-30 years, making waste material disposal a major issue. Recently, buildings with the goal of reaching a lifespan of 100 years have begun to emerge, leading to an increasing demand for materials with excellent durability.
