Dual Use for Hardware & Car Mod: Designed to excel in both hardware tasks (metal brackets, machinery) and car modification (engine parts, chassis), offering versatile fastening solutions for diverse needs.
10.9-Grade Strength & Hex Flange: 1000MPa tensile/900MPa yield strength resists vibration/impacts; integrated flange acts as a built-in washer (prevents damage, no extra washers needed) for easy, secure installation.
Color-Zinc Rust Protection: Thick, uniform plating shields against moisture, salt spray, oil, and chemicals, ensuring long-term rust resistance and reducing maintenance/replacement costs.
Precise Quality : Each screw passes precision/hardness tests (no burrs/defects)
