Carbon steel oil plug bolt

El proceso de estampado en frío es uno de los nuevos procesos de mecanizado a presión de menor o ningún corte
metal. Es un método de transformación que utiliza la deformación plástica del metal bajo la acción de
fuerzas externas y, con ayuda de moldes, redistribuye y transfiere el volumen de metal para formar
las piezas o formatos necesarios. El proceso de estampación en frío es el más adecuado para producir piezas estándar.
elementos de fijación como pernos, tornillos, tuercas, remaches, pasadores, etc.

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.

• Tipo de hilo: 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.

• Maquinaria industrial – 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.
