ELRING 004.260 Nuts And Bolts

Product Overview

ELRING 004.260 Nuts And Bolts is a high‑performance cylinder head bolt kit engineered for precision and durability in automotive engine assemblies. Designed to replace or upgrade the original fasteners on a wide range of engines, this kit delivers superior strength, consistent torque application, and long‑term reliability.

Key Features

• Material Composition: Each bolt is forged from high‑strength alloy steel with a chrome‑plated finish to resist corrosion and wear.
• Thread Specification: Metric M10 × 1.5 threads, matching the standard cylinder head bolt size for many modern engines.
• Hexagonal Head: External hexagon design allows easy engagement with torque wrenches and ensures accurate tightening.
• Heat Treatment: All bolts undergo a rigorous heat‑treatment process to achieve a tensile strength of at least 850 MPa, guaranteeing structural integrity under high compression pressures.
• Pre‑Tightened Torque Sequence: The kit includes a detailed torque sequence diagram and recommended torque values (typically 70–80 Nm) for each bolt position.
• Compatibility Range: Suitable for engines from manufacturers such as Mitsubishi, BYD, Changan, Proton, and others that use the 004.260 specification.

Technical Specifications

Installation Guide

1. Preparation: Clean the cylinder head and engine block surfaces. Remove any old fasteners, debris, or residue.
2. Alignment: Position each bolt in its designated slot, ensuring proper alignment with the head gasket and valve seats.
3. Tightening Sequence: Follow the recommended torque sequence: first tighten all bolts to a low torque (≈ 30 Nm), then progressively increase to the final value (70–80 Nm) in a cross‑pattern to distribute pressure evenly.
4. Verification: Use a calibrated torque wrench and double‑check each bolt. Inspect for any signs of misalignment or uneven gaps.
5. Final Check: After the full tightening cycle, perform a leak test on the head gasket to confirm proper sealing.

Benefits of Using ELRING 004.260 Nuts And Bolts

• Enhanced Engine Longevity: The high‑strength bolts reduce the risk of bolt failure, which can lead to catastrophic engine damage.
• Consistent Performance: Precise torque application ensures uniform compression across all cylinders, improving fuel efficiency and power output.
• Corrosion Protection: Chrome plating extends service life in harsh operating environments, such as high humidity or salt exposure.
• Ease of Maintenance: Standardized dimensions allow for quick replacement during routine servicing or after engine rebuilds.

Applications and Compatibility

The ELRING 004.260 kit is engineered to fit a broad spectrum of engines that utilize the 004.260 specification. Common applications include:

• Mitsubishi gasoline and diesel engines (e.g., 4G63, 4G64)
• BYD passenger car engines
• Changan and Chana models with similar head bolt layouts
• Proton vehicles that employ the 004.260 bolt pattern
• Other OEMs and aftermarket engines that match the metric M10 × 1.5 thread standard.

Quality Assurance & Compliance

Each batch of ELRING 004.260 bolts undergoes rigorous testing:

• Tensile Strength Test: Samples are pulled to failure to confirm compliance with the ≥ 850 MPa requirement.
• Hardness Verification: Rockwell B hardness is measured to ensure consistency across the lot.
• Corrosion Resistance Assessment: Salt spray tests simulate marine and road salt exposure, verifying the durability of the chrome plating.
• Dimensional Accuracy: Micrometer checks confirm thread pitch, head diameter, and bolt length within ±0.02 mm tolerance.

Environmental Considerations

The manufacturing process for ELRING 004.260 bolts adheres to strict environmental standards:

• Low Emission Production: Heat‑treatment furnaces are equipped with catalytic converters to reduce CO₂ output.
• Recyclable Materials: The alloy steel used can be fully recycled at the end of its service life, minimizing landfill waste.
• Eco‑Friendly Coatings: Chrome plating is applied using a closed‑loop system that recycles excess chemicals and reduces hazardous waste.

Maintenance & Longevity Tips

1. Regular Inspection: During routine engine overhauls, check bolt torque values to ensure they remain within the specified range.
2. Avoid Over‑Tightening: Excessive torque can strip threads or crack the head gasket; use a calibrated wrench and follow the recommended sequence.
3. Protect from Corrosion: If operating in high‑salt environments, consider additional anti‑rust treatments on exposed surfaces.
4. Use Compatible Gaskets: Pair the bolts with gaskets that match the engine’s compression and temperature requirements to prevent leaks.

Conclusion

The ELRING 004.260 Nuts And Bolts kit represents a blend of engineering precision, material excellence, and practical design. By providing reliable fastening solutions for critical engine components, it safeguards performance, enhances durability, and simplifies maintenance across a diverse range of automotive platforms.
