Automotive hardware encompasses non-moving, mechanically fastened components used throughout vehicle assembly. This category includes fasteners like bolts, nuts, and screws, as well as clips, brackets, and retaining rings. These parts secure body panels, affix components to the chassis, and join mechanical assemblies. Materials commonly include carbon steel, alloy steel, and stainless steel, often with protective coatings for corrosion resistance. Grade markings indicate tensile strength, crucial for safety-critical applications, while specialized designs address vibration, temperature, and load requirements. Hardware is specified by dimensions, thread type, material, and finish to ensure proper fit and function.
