Oil plug screw black oxide

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.

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
