Oil plug screw black oxide

عملية الرأس على البارد هي واحدة من العمليات الجديدة للتشغيل الآلي بالضغط ذات القطع الأقل أو بدون قطع
المعدن. وهي طريقة معالجة تستخدم التشوه البلاستيكي للمعدن تحت تأثير
قوى خارجية، وبمساعدة القوالب، تقوم بإعادة توزيع ونقل حجم المعدن لتشكيل
الأجزاء أو الفراغات المطلوبة. عملية الخراطة على البارد هي الأكثر ملاءمة لإنتاج الأجزاء القياسية
أدوات التثبيت مثل البراغي والبراغي والصواميل والمسامير والمسامير والدبابيس وغيرها

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
