Oil plug screw black oxide

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.

A black oxide oil plug screw is a high-quality, corrosion-resistant drain plug designed for securing an engine’s oil pan while providing enhanced durability and a sleek, low-reflective black finish. Commonly used in automotive, motorcycle, and industrial applications, it combines functionality with an aesthetic upgrade over standard silver-colored plugs.

Key Characteristics

1. Black Oxide Finish

• Process: Created through a chemical conversion coating that bonds with the metal surface.

• Appearance: Smooth, uniform matte black finish.

• Benefits:

  • Improved corrosion resistance compared to untreated steel.

  • Reduced light glare, ideal for performance or custom builds.

  • Slight oil retention properties for minor rust prevention. Oil plug screw black oxide

2. Material & Durability

• Base Metal: High-carbon or alloy steel for strength.

• Magnetic Option: Some versions include a magnetic tip to trap metal particles.

3. Design Features

• Head Types:

  • Allen/Hex Key Drive: Low-profile, sleek appearance.

  • Square Drive: Heavy-duty applications.

• Sealing:

  • Requires a crush washer (often included) for a tight seal.

  • Some models feature an integrated O-ring groove for double sealing. Oil plug screw black oxide

4. Performance Benefits

✔ Moderate Rust Protection – Better than raw steel but less than zinc or stainless.
✔ Aesthetic Upgrade – Popular in blacked-out or custom engine bays.

Common Applications

• Automotive: Cars, trucks, SUVs (especially modified/show vehicles).

• Industrial/Marine Equipment: Resists moisture in harsh environments.

Installation Tips

1. Always use a new crush washer to prevent leaks.

2. Avoid over-tightening to prevent oil pan thread damage.

3. Inspect periodically for coating wear or rust in harsh climates. Oil plug screw black oxide
