Automotive hardware encompasses non-moving, mechanically fastened components integral to vehicle assembly and system securement. This category includes fasteners like bolts, nuts, and screws, alongside clips, brackets, and retaining rings used throughout the chassis, body, powertrain, and interior. Materials are typically high-strength steel, alloy steel, or corrosion-resistant polymers, often with specialized coatings for environmental protection. Hardware is characterized by specific thread types (metric, UNC, UNF), head styles, and grade markings indicating tensile strength. Precise dimensional control and adherence to OEM specifications are critical for proper fitment and functional reliability.
