Carbon steel oil plug bolt

Das Kaltstauchverfahren ist eines der neuen Verfahren für die Druckbearbeitung mit weniger oder gar keiner Zerspanung
Metall. Es handelt sich um eine Verarbeitungsmethode, die die plastische Verformung von Metall unter der Einwirkung von
äußere Kräfte, und mit Hilfe von Formen wird das Metallvolumen umverteilt und in die Form gebracht
die gewünschten Teile oder Rohlinge. Das Kaltstauchverfahren ist am besten geeignet für die Herstellung von Standard
Verbindungselemente wie Bolzen, Schrauben, Muttern, Nieten, Stifte usw.

Carbon steel oil plug bolt are heavy-duty fasteners designed for sealing oil pans, transmission systems, and other fluid compartments in automotive, industrial, and machinery applications. They are known for their high strength, durability, and cost-effectiveness compared to stainless steel or alloy alternatives.

1. Material & Construction

• Base Material: Made from medium/high-carbon steel (e.g., Grade 5, Grade 8, or ASTM A574) for superior tensile strength.

• Surface Treatment: Typically zinc-plated (electro-galvanized), black oxide, or plain oil-finished for basic corrosion resistance.

• Gewindetyp: Standard metric (M12x1.75, M14x1.5) or SAE (1/2″-20, 3/4″-16) threads, with fine or coarse pitch options.

• Magnetic Properties: Some variants include magnetic tips to capture metal shavings in oil systems.

2. Common Applications

• Automotive Oil Drain Plugs – Used in engine oil pans, differentials, and transmissions.

• Industrielle Maschinen – Hydraulic systems, gearboxes, and pump housings.

• Heavy Equipment – Tractors, excavators, and diesel engines.

• Marine & Agricultural Machinery – Where moderate corrosion resistance is sufficient.

3. Maintenance & Considerations

• Torque Properly – Over-tightening can strip threads; use a torque wrench.

• Replace Washers – Crush washers should be replaced after each removal.

• Check for Rust – If uncoated, carbon steel can corrode in wet conditions.

• Thread Compatibility – Ensure correct size (e.g., M12x1.75 for many Japanese cars).

Conclusion

Carbon steel oil plug bolt are strong, economical, and widely used in automotive and industrial applications. While they require protective coatings to resist rust, their durability and affordability make them a popular choice for oil drain and fluid system sealing.
