Toothed nut black plating

主要功能
  • Nylon Insert (Nyloc Nut): Contains a nylon ring that creates friction to resist vibration loosening. Reusable in some cases.

  • Metal Locking (All-Metal Nut): Features a crimped top, deformed threads, or a flange with serrations for a permanent grip.

  • Prevailing Torque Nut: Uses distorted threads or a conical top to maintain tension.

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
  • Purpose: 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.
