ELRING 130.850 Nuts And Bolts

Elring 130.850 Nuts And Bolts: The Cornerstone of Engine Reliability

The Elring 130.850 Nuts and Bolts are a meticulously engineered component set designed to secure the cylinder head to the engine block with uncompromising precision. These fasteners form an essential part of the internal combustion engine’s structural integrity, ensuring that the head remains firmly attached under extreme pressure, temperature, and vibration conditions.

Key Design Features

• M11 x 1.5 x 133 mm thread size – a standard dimension that guarantees compatibility with a wide range of European engines.
• High‑strength alloy steel construction – offers superior tensile strength and resistance to fatigue, extending the service life of each bolt.
• Heat treatment and surface hardening – provides excellent wear resistance and protects against galling during installation.
• Split‑head design – allows for uniform torque distribution across all fasteners, preventing uneven clamping forces that could lead to head warping.
• Precision machining – ensures a tight fit and eliminates play between the bolt head and the cylinder head mounting surface.

Compatibility Spectrum

The Elring 130.850 Nuts and Bolts are engineered to fit a broad array of vehicles, predominantly within the Volkswagen Group ecosystem. Their versatility extends to:

• Audi A4, A6, A8, Allroad, C5, B5, B6
• Volkswagen Passat (including Variant and 3B3/3B6 models)
• Skoda Superb, Skoda Octavia, and other Skoda models
• Hongqi, Seat, Cupra, and related platforms
• Various engine displacements (2.4 L, 2.8 L V6, etc.)

Because the bolt set is a direct OEM replacement, it adheres to the same specifications used during original assembly, guaranteeing seamless integration into existing engine designs.

Installation Excellence

Proper installation of the Elring 130.850 Nuts and Bolts is critical for maintaining head gasket integrity and preventing leaks. Follow these best practices:

1. Torque Sequence: Apply torque in a cross‑pattern, gradually increasing to the specified value (typically 140 Nm). This ensures even clamping pressure.
2. Tightening Speed: Use a calibrated torque wrench and avoid over‑tightening, which can strip threads or damage the head.
3. Thread Lubrication: Apply a suitable thread lubricant to reduce friction and improve torque accuracy.
4. Inspection: After tightening, inspect each bolt for proper seating and absence of cross‑threading.

Performance Benefits

When installed correctly, the Elring 130.850 Nuts and Bolts deliver:

• Enhanced Head Gasket Life: By maintaining consistent clamping force, they reduce the risk of gasket failure.
• Improved Engine Durability: Their high‑strength material resists deformation under high compression pressures.
• Consistent Thermal Expansion Management: The bolts accommodate thermal cycling without compromising seal integrity.
• Reduced Maintenance Intervals: Reliable fastening reduces the need for frequent head gasket replacements.

Quality Assurance and Standards

The Elring 130.850 Nuts and Bolts are manufactured under stringent quality control protocols, including:

• ISO 9001 certification – ensuring consistent production processes.
• Material traceability – each batch is documented for source verification.
• Dimensional inspection – micrometer and caliper checks guarantee adherence to specified tolerances.
• Functional testing – torque and fatigue tests confirm performance under simulated engine conditions.
