Automotive hardware encompasses non-moving, mechanically fastened components utilized throughout vehicle assembly. This category includes fasteners like bolts, nuts, screws, and washers, as well as clips, brackets, and retaining hardware. Materials typically consist of carbon steel, alloy steel, or stainless steel, often with protective coatings for corrosion resistance. Hardware secures body panels, supports chassis components, and assembles mechanical systems – engines, transmissions, and interiors. Precise thread standards (metric, UNC, UNF) and grade markings define load-bearing capacity and application suitability. Specialized hardware includes self-locking nuts, flange fasteners, and tamper-resistant designs for specific functions and security requirements.
