M10x130 Steel HF Bolt for Tesla Model 3/Y (2017-2023) | 1446114-00-B

1. Key Specifications & Compatibility

2. Why This Brand-Grade HF Bolt Is Critical for Your Model 3/Y

1. High Strength for Critical Loads: Steel[109] grade delivers 1000+ MPa tensile strength, meaning it can withstand heavy forces (e.g., suspension impacts from potholes, body torsion during turns) without bending, stretching, or breaking—unlike low-grade bolts that fail under stress.
2. ZNFL Coating Prevents Corrosion: Road salt, rain, and humidity often cause standard bolts to rust and seize (making future maintenance impossible). ZNFL plating forms a protective barrier that resists corrosion for 5+ years, ensuring the bolt remains removable and functional.
3. Precision Dimensional Fit: Exact M10x130 thread pitch and shank length match Model 3/Y’s factory mounting holes. Substandard bolts with mismatched threads can strip holes or loosen over time—leading to component wobble or failure.
4. Vibration Resistance: The coarse ISO thread design and high-tensile material ensure the bolt stays tight under constant vehicle vibration (e.g., highway driving, rough roads), preventing dangerous component loosening (e.g., suspension brackets shifting).

3. What It Actually Does (No Tech Jargon)

• Secures Key Components: This bolt fastens critical parts like suspension brackets or subframe mounts to your Model 3/Y’s body or chassis—think of it as a “strong link” that keeps heavy components in place, even when driving over bumps or potholes.
• Won’t Rust or Seize: The ZNFL coating means it won’t rust, even if you drive in snowy areas (where roads are salted) or rainy climates. Rusty bolts often get stuck, making repairs impossible without drilling them out—this one avoids that hassle.
• Handles Heavy Force: Unlike cheap bolts that bend if you tighten them too much (or snap under stress), the Steel[109] material is tough enough to handle the torque needed to keep components secure—no risk of the bolt failing when you need it most.
• Fits Like Factory: It’s the exact size (M10x130) and thread pattern Tesla uses—so it screws into factory holes perfectly, no forcing or stripping threads.

4. Signs You Need to Replace This Bolt

• Visible Rust/Corrosion: The bolt’s surface is rusted, flaking, or discolored (ZNFL coating has failed, and the steel is now at risk of weakening).
• Bolt Damage: The bolt is bent, stripped (threads are worn), or has a cracked head (can’t be safely tightened or will fail under load).
• Component Loosening: The part fastened by this bolt (e.g., suspension bracket) feels wobbly or makes rattling noises—signals the bolt is loose or has stretched.
• After Repairs: If you’re replacing suspension, subframe, or body components that use this bolt, always install a new one (used bolts may have hidden stress damage that leads to failure).
• Seized Bolt: The old bolt is stuck (rusted in place) and had to be drilled out or cut during maintenance—requires a new bolt to resecure the component.

5. Why This Brand-Grade Bolt Outperforms Generic Alternatives

• Genuine Steel[109] Strength: Generic bolts often claim “high strength” but use low-grade steel (e.g., 8.8 grade, 800 MPa tensile strength) that bends or snaps under stress. This one uses authentic Steel[109] (1000 MPa), matching Tesla’s factory strength.
• Authentic ZNFL Coating: Generic bolts use cheap zinc plating that rusts in 6–12 months. ZNFL coating (used here) is thicker and more chemical-resistant, lasting 5+ years in harsh conditions.
• Precision Threads: Generic bolts have inconsistent thread patterns (too loose or too tight), which strip factory mounting holes. This bolt’s ISO-standard threads match Model 3/Y’s holes exactly, avoiding damage.
• Torque Compliance: Generic bolts can’t handle Tesla’s 55–65 Nm torque spec (either break when tightened or stretch and loosen). This one is calibrated to withstand the factory torque range, ensuring a secure fit.

6. Installation & What You Receive

• 1x M10x130 Steel[109] HF Bolt (1446114-00-B)
• Digital Installation Guide: Step-by-step tips, including recommended torque tools (e.g., torque wrench to apply 55–65 Nm), how to clean mounting holes before installation (to avoid thread damage), and best practices for tightening (e.g., don’t use impact wrenches—they can over-tighten and damage the bolt).
