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 hardware. Materials commonly include carbon steel, alloy steel, and corrosion-resistant variants for durability. Dimensional precision and thread standards (metric, SAE) are critical for proper fit and function. Hardware secures body panels, supports chassis components, and fastens interior/exterior trim, ensuring structural integrity and component retention. Specialized coatings, like zinc or phosphate, provide environmental protection and prevent galling.
