The price range for fasteners used in new energy vehicles varies greatly depending on the material, performance grade, and application scenario. The unit price for ordinary parts ranges from 0.1 to 5 yuan, while high-performance special-purpose parts can reach 5 to 50 yuan or even higher. The following is a detailed classification:
1. Conventional Metal Fasteners (Steel/Stainless Steel)
Price Range: 0.1–3 yuan/piece
Application Scenarios: Non-core high-pressure areas such as body structure, chassis, and interior/exterior trim
Features: Standard parts design, low cost for bulk purchases, e.g., M6 8.8 grade bolts are approximately 0.5 yuan, stainless steel clips are approximately 1.2 yuan.
2. High-Strength Fasteners (8.8 grade and above)
Price Range: 2–8 yuan/piece
Application Scenarios: Suspension system, motor bracket, battery pack frame connection
Features: Must meet tensile strength ≥800MPa, some use 12.9 grade alloy steel, complex heat treatment process, higher cost
3. Lightweight Fasteners (Aluminum Alloy/Titanium Alloy/Composite Materials)
Price Range: 5–30 RMB/piece
Application Scenarios: Internal connections in battery packs, fixing of electronic control units, lightweight body modules
Features: Aluminum alloy bolts are priced at approximately 8–15 RMB each, with low density but strength approaching that of steel components. Titanium alloy fasteners can reach 20–30 RMB each, used in key weight-reduction components of high-end vehicles. PEEK engineering plastic screws are priced at approximately 10–25 RMB each, possessing excellent insulation and temperature resistance.
