Hardware

Automotive hardware encompasses non-moving, typically metallic components used to mechanically fasten or secure vehicle systems. These parts include bolts, nuts, screws, washers, clips, and pins, found throughout chassis, body, powertrain, and accessory applications. Materials commonly include carbon steel, alloy steel, and stainless steel, often with protective coatings like zinc or phosphate for corrosion resistance. Grade markings indicate tensile strength and are critical for proper component selection, especially in safety-critical areas. Fastener thread types are standardized (UNC, UNF, metric fine/coarse) and must match mating components for secure assembly. Variations include specialized head styles, drive types, and self-locking features to meet specific application requirements.
