Toothed nut black plating

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 safety thread nut with a black coating is a specialized fastener designed to resist loosening under vibration or torque while also providing corrosion resistance and a sleek, dark appearance. Here’s a general description of its features:

1. Safety Thread Design

• Locking Mechanism: Typically features a nylon insert (nyloc nut), deformed threads, or a metal locking collar to prevent self-loosening.

• Reusable or One-Time Use: Some (like nylon insert nuts) can be reused, while others (like crimped-top nuts) are single-use.

2. Black Coating

• Zweck: Enhances corrosion resistance and provides an aesthetic black finish.

• Common Coatings:

  • Black Oxide: Offers moderate corrosion resistance and a matte black finish.

  • Zinc Plating (Black): Provides better corrosion protection with a black chromate finish.

  • Phosphate Coating: Often used for lubrication and mild corrosion resistance.

  • Dacromet/Geomet: Advanced corrosion-resistant coatings with a dark gray/black hue.

  • Powder Coating/Paint: Used for decorative or heavy-duty environmental protection.

3. Material & Strength

• Base Metal: Typically steel (grade 8, 10, or 12), stainless steel (A2/A4), or brass.

• Strength Class: Markings (e.g., 8, 10, or 12) indicate tensile strength.

4. Applications

• Automotive & Aerospace: Vibration-prone environments.

• Machinery & Industrial Equipment: Where secure fastening is critical.

• Outdoor/Marine Use: Black-coated nuts resist weathering.

• Aesthetic Applications: Black-coated nuts are used in visible assemblies (e.g., furniture, electronics).

• Toothed nut black plating

5. Standards & Certifications

• DIN, ISO, ASTM, or SAE compliance ensures quality and performance.

• RoHS/REACH compliant if used in regulated industries.

• Toothed nut black plating

6. Advantages

• Vibration Resistance: Prevents loosening.

• Corrosion Protection: Black coating adds durability.

• Aesthetic Appeal: Uniform black finish for a professional look.
